## Answers to Questions (FAQ)

### 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.

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 write numbers in letters?

dCode provides another tool for writing numbers into letters.

### 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:

billion | 1000000000 | 9 zeros |

trillion | 1000000000000 | 12 zeros |

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.
