### What is the writing in digits of a number? (Definition)

Numbers are particular words (or compound words) which have a writing in letters (ONE, TWO, THREE, etc.) but also, more commonly a dedicated writing in numbers (1, 2, 3, etc).

Numerical writing is used for its simplicity (more abbreviated notation) and its ease of understanding, it is also the preferred mathematical writing.

### How to convert a number from letters to figures?

Conversion is based on English writing rules. The writing of numbers in whole letters in English follows some syntactic rules. dCode reads the words and recomposes the numbers.

Example: one hundred twenty-three corresponds to 123

 zero 0 one 1 two 2 three 3 four 4 five 5 six 6 seven 7 eight 8 nine 9 ten 10 eleven 11 twelve 12 thirteen 13 fourteen 14 fifteen 15 sixteen 16 seventeen 17 eighteen 18 nineteen 19 twenty 20 twenty-one 21 twenty-two 22 twenty-three 23 twenty-four 24 twenty-five 25 thirty 30 forty 40 fifty 50 sixty 60 seventy 70 eighty 80 ninety 90 hundred 100 thousand 1000 million 1000000 billion 1000000000 another number? use the form on top of this page!

To write large numbers, in typography, it is advisable to put a comma every thousand, but this notation is ambiguous in computing, so not recommended in this domain.

### How to read big numbers?

To read large numbers, divide the number into groups of three digits (starting from the right). Then read each group using the corresponding words, adding the name of the appropriate power of ten (thousand, million, billion, etc.) between each group.

Beyond billions, it is better to use the scientific notation, if it is not the case, here is a table of the names of the big numbers:

Among the greatest numbers with a name, there are also more exotic names like the gogol which is worth $10^{100}$ that is the number 1 followed by 100 zeros or the gogolplex which is worth $10^{10^{100}}$ or the number 1 followed by a gogol of zeros.

When writing currencies (euros, dollars, etc.) some subunits can be used, like the cents 0.01, or in India the lakh is worth 100000

### Where to set commas in numbers?

A comma is sometimes positioned every 3 digits to the left of the decimal point (especially for large numbers, so that they are easy to read).

The international system of units recommends the use of (thin space).

dCode avoids writing numbers with commas because they cause computer problems (for a computer, a number should never commas)

### What is the difference between cardinal numbers and ordinal numbers?

Cardinal numbers, such as one, two, three, etc., indicate a quantity or value (1, 2, 3, etc.).

Ordinal numbers, like first, second, third, etc., indicate order or position in a sequence.
