In American usage, four-digit numbers with non-zero hundreds are often named using multiples of "hundred" and combined with tens and ones: "One thousand one", "Eleven hundred three", "Twelve hundred twenty-five", "Four thousand forty-two", or "Ninety-nine hundred ninety-nine." In British usage, this style is common for multiples of 100 between 1,000 and 2,000 (e.g. 1,500 as "fifteen hundred") but not for higher numbers.

Americans may pronounce four-digit numbers with non-zero tens and ones as pairs of two-digit numbers without saying "hundred" and inserting "oh" for zero tens: "twenty-six fifty-nine" or "forty-one oh five". This usage probably evolved from the distinctive usage for years; "nineteen-eighty-one". It is avoided for numbers less than 2500 if the context may mean confusion with time of day: "ten ten" or "twelve oh four".

Intermediate numbers are read differently depending on their use. Their typical naming occurs when the numbers are used for counting. Another way is for when they are used as labels. The second column method is used much more often in American English

. The third column is used in British English, but rarely in American English (although the use of the second and third columns is not necessarily directly interchangeable between the two regional variants). In other words, the British dialect can seemingly adopt the American way of counting, but it is specific to the situation (in this example, bus numbers).

, many students are taught not to use the word and anywhere in the whole part of a number, so it is not used before the tens and ones. It is instead used as a verbal delimiter when dealing with compound numbers. Thus, instead of "three hundred and seventy-three", one would say "three hundred seventy-three". For details, see American and British English differences.

For numbers above a million, there are two different systems for naming numbers in English (for the use of prefixes such as kilo- for a thousand, mega- for a million, milli- for a thousandth, etc. see SI units):

the long scale
Long and short scales
The long and short scales are two of several different large-number naming systems used throughout the world for integer powers of ten. Many countries, including most in continental Europe, use the long scale whereas most English-speaking countries use the short scale...

Number notation	Power notation	Short scale	Long scale
1,000,000	10⁶	one million Million One million or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione , from mille, "thousand", plus the augmentative suffix -one.In scientific notation, it is written as or just 106...	one million
1,000,000,000	10⁹	one billion a thousand million	one milliard a thousand million
1,000,000,000,000	10¹²	one trillion a thousand billion	one billion a million million
1,000,000,000,000,000	10¹⁵	one quadrillion a thousand trillion	one billiard a thousand billion
1,000,000,000,000,000,000	10¹⁸	one quintillion a thousand quadrillion	one trillion a million billion
1,000,000,000,000,000,000,000	10²¹	one sextillion a thousand quintillion	one trilliard a thousand trillion

The numbers past a trillion, in ascending powers of ten, are as follows: quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion, undecillion, duodecillion, tredecillion, quattuordecillion, and quindecillion (that's 10 to the 48th, or a one followed by 48 zeros). The highest number listed on Robert Munafo's table, is a milli-millillion. That's 10 to the 3000003rd.

The googolplex has often been nominated as the largest named number in the world. If a googol is ten to the one hundredth, then a googolplex is one followed by a googol of zeroes.

Although British English has traditionally followed the long-scale numbering system, the short-scale usage has become increasingly common in recent years. For example, the UK Government and BBC websites use the newer short-scale values exclusively.

Here are some approximate composite large numbers in American English:

Quantity	Written	Pronounced
1,200,000	1.2 million Million One million or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione , from mille, "thousand", plus the augmentative suffix -one.In scientific notation, it is written as or just 106...	one point two million
3,000,000	3 million	three million

6,400,000,000	6.4 billion	six point four billion
23,380,000,000	23.38 billion	twenty-three point three eight billion

Often, large numbers are written with (preferably non-breaking) half-spaces or thin spaces separating the thousands (and, sometimes, with normal space

Combinations of numbers in most sports scores are read as in the following examples:

1–0 British English: one nil; American English: one-nothing, one-zip, or one-zero
0–0 British English: nil-nil, or nil all; American English: zero-zero or nothing-nothing, (occasionally scoreless or no score)
2–2 two-two or two all; American English also twos, two to two, even at two, or two up.)

Multiplicative numerals

A few numbers have specialised multiplicative numerals expresses how many fold or how many times:

one time	once
two times	twice
three times	thrice

Negative numbers

The name of a negative number is the name of the corresponding positive number preceded by "minus" or (American English) "negative". Thus -5.2 is "minus five point two" or "negative five point two". For temperatures, Americans colloquially say "below" —short for "below zero"— so a temperature of -5 ° is "five below".

context.

Ordinal numbers such as 21st, 33rd, etc., are formed by combining a cardinal ten with an ordinal unit.

21st	twenty-first
25th	twenty-fifth
32nd	thirty-second
58th	fifty-eighth
64th	sixty-fourth
79th	seventy-ninth
83rd	eighty-third
99th	ninety-ninth

Higher ordinals are not often written in words, unless they are round numbers (thousandth, millionth, billionth). They are written using digits and letters as described below. Here are some rules that should be borne in mind.

The suffixes -th, -st, -nd and -rd are occasionally written superscript above the number itself.
If the tens digit of a number is 1, then write "th" after the number. For example: 13th, 19th, 112th, 9,311th.
If the tens digit is not equal to 1, then use the following table:

If the units digit is: 0 1 2 3 4 5 6 7 8 9
write this after the number th st nd rd th th th th th th
For example: 2nd, 7th, 20th, 23rd, 52nd, 135th, 301st.

If the units digit is:	0	1	2	3	4	5	6	7	8	9
write this after the number	th	st	nd	rd	th	th	th	th	th	th

These ordinal abbreviations are actually hybrid contractions of a numeral and a word. 1st is "1" + "st" from "first". Similarly, we use "nd" for "second" and "rd" for "third". In the legal field and in some older publications, the ordinal abbreviation for "second" and "third" is simply, "d".

For example: 42d, 33d, 23d

NB: The practice of using "d" to denote "second" and "third" is still often followed in the numeric designations of units in the US armed forces, for example, 533d Squadron.

Any ordinal name that doesn't end in "first", "second", or "third", ends in "th".

Fractions and decimals

In spoken English, ordinal numbers are also used to quantify the denominator of a fraction. Thus 'fifth' can mean the element between fourth and sixth, or the fraction created by dividing the unit into five pieces. In this usage, the ordinal numbers can be pluralized: one seventh, two sevenths. The sole exception to this rule is division by two. The ordinal term 'second' can only refer to location in a series; for fractions English speakers use the term 'half' (plural 'halves').

Here are some common fraction

Fraction (mathematics)

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, we specify how many parts of a certain size there are, for example, one-half, five-eighths and three-quarters.A common or "vulgar" fraction, such as 1/2, 5/8, 3/4, etc., consists...

s (partitive numerals):

1/16	one-sixteenth
1/10 or 0.1	one-tenth
1/8	one-eighth
2/10 or 0.2	two-tenths
1/4	one-quarter or (mainly American English) one-fourth
3/10 or 0.3	three-tenths
1/3	one-third
3/8	three-eighths
4/10 or 0.4	four-tenths
1/2	one half
6/10 or 0.6	six-tenths
5/8	five-eighths
2/3	two-thirds
7/10 or 0.7	seven-tenths
3/4	three-quarters or three-fourths
8/10 or 0.8	eight-tenths
7/8	seven-eighths
9/10 or 0.9	nine-tenths
15/16	fifteen-sixteenths

Alternatively, and for greater numbers, one may say for 1/2 "one over two", for 5/8 "five over eight", and so on. This "over" form is also widely used in mathematics. (This form is not common in British English.)

Numbers with a decimal point may be read as a cardinal number, then "and", then another cardinal number followed by an indication of the significance of the second cardinal number (not common in British English); or as a cardinal number, followed by "point", and then by the digits of the fractional part. The indication of significance takes the form of the denominator of the fraction indicating division by the smallest power of ten larger than the second cardinal. This is modified when the first cardinal is zero, in which case neither the zero nor the "and" is pronounced, but the zero is optional in the "point" form of the fraction.

For example:
- 0.002 is "two thousandths" (mainly U.S.); or "point zero zero two", "point oh oh two", "nought point zero zero two", etc.
- 3.1416 is "three point one four one six"
- 99.3 is "ninety-nine and three tenths" (mainly U.S.); or "ninety-nine point three".

In English the decimal point was originally printed in the center of the line (0·002), but with the advent of the typewriter it was placed at the bottom of the line, so that a single key could be used as a full stop/period and as a decimal point. In many non-English languages a full-stop/period at the bottom of the line is used as a thousands separator with a comma being used as the decimal point.

Fractions together with an integer are read as follows:
- 1 1/2 is "one and a half"
- 6 1/4 is "six and a quarter"
- 7 5/8 is "seven and five eighths"

A space is required between the whole number and the fraction; however, if a special fraction character is used like "½", then the space can be done without, e.g.

- 9 1/2
- 9½

Whether to use digits or words

According to most copy editors and English teachers, the numbers zero to nine inclusive should be "written out" – meaning instead of "1" and "2", one would write "one" and "two".

Example: "I have two apples." (Preferred)

Example: "I have 2 apples."

After "nine", one can head straight back into the 10, 11, 12, etc., although some write out the numbers until "twelve".

Example: "I have 28 grapes." (Preferred)

Example: "I have twenty-eight grapes."

Another common usage is to write out any number that can be expressed as one or two words, and use figures otherwise.

Examples:

"There are six million dogs." (Preferred)

"There are 6,000,000 dogs."

"That is one hundred twenty-five oranges."

"That is 125 oranges." (Preferred)

Numbers at the beginning of a sentence should also be written out.

The above rules are not always used. In literature, larger numbers might be spelled out. On the other hand, digits might be more commonly used in technical or financial articles, where many figures are discussed. In particular, the two different forms should not be used for figures that serve the same purpose; for example, it is inelegant to write, "Between day twelve and day 15 of the study, the population doubled."

Empty numbers

Colloquial English has a small vocabulary of empty numbers that can be employed when there is uncertainty as to the precise number to use, but it is desirable to define a general range: specifically, the terms "umpteen", "umpty", and "zillion

Zillion

A zillion is a fictitious, indefinitely large number.Zillion or Zillions may also refer to:* Zillion , a 1987 Japanese anime series, and its spinoffs:** Zillion: Burning Night, a 1988 direct-to-video release...

". These are derived etymologically from the range affixes:

"-teen" (designating the range as being between 10 and 20)
"-ty" (designating the range as being in one of the decades between 20 and 100)
"-illion" (designating the range as being above 1,000,000; or, more generally, as being extremely large).

The prefix "ump-" is added to the first two suffixes to produce the empty numbers "umpteen" and "umpty": it is of uncertain origin. There is a noticeable absence of an empty number in the hundreds range.

Usage of empty numbers:

The word "umpteen" may be used as an adjective, as in "I had to go to umpteen stores to find shoes that fit." It can also be used to modify a larger number, usually "million", as in "Umpteen million people watched the show; but they still cancelled it."
"Umpty" is not in common usage. It can appear in the form "umpty-one" (parallelling the usage in such numbers as "twenty-one"), as in "There are umpty-one ways to do it wrong." "Umpty-ump" is also heard, though "ump" is never used by itself.
The word "zillion" may be used as an adjective, modifying a noun. The noun phrase normally contains the indefinite article "a", as in "There must be a zillion sites on the World Wide Web."
The plural "zillions" designates a number indefinitely larger than "millions" or "billions". In this case, the construction is parallel to the one for "millions" or "billions", with the number used as a plural count noun, followed by a prepositional phrase with "of", as in "Out in the countryside, the night sky is filled with zillions of stars."
Empty numbers are sometimes made up, with obvious meaning: "squillions" is obviously an empty, but very large, number; a "squintillionth" would be a very small number.
Some empty numbers may be modified by actual numbers, such as "four zillion", and are used for jest, exaggeration, or to relate abstractly to actual numbers.
Empty numbers are colloquial, and primarily used in oral speech or informal contexts. They are inappropriate in formal or scholarly usage.
