## Answers to Questions (FAQ)

### What is a 32 bit integer? (Definition)

A 32-bit integer is a data type in computing that can store an integer value in 32 bits (4 bytes) of memory.

### What is the difference between a signed and unsigned integer?

32-bit stored integers theoretically allow counting between $0$ and $2^{32}-1 = 4294967295$ for an unsigned integer.

It is possible to use a bit to indicate the sign (+ or -) of the number in order to sign it, and have a value between $-2^{31} = 2147483648$ and $2^{31}-1 = 2147483647$. This representation is called two's complement.

### How to encode with 32 bit integers?

Any message can be computer coded in binary (thus on bits). By interpreting each 32-bit block as numbers, a message can be encoded as a series of numbers.

Example: dCode can be coded 01100100,01000011,01101111,01100100,01100101 in binary (ASCII coding). The first 32 bits translate the number 1685013348, then the sequence is 101.

If the message does not have a length multiple of 32 bits, padded with null bytes

### How to decode 32 bit integers?

Integers must be converted to binary and then interpreted with the appropriate encoding (usually ASCII or Unicode) to obtain intelligible text.

Example: The number 1685013348 is converted to 1100100010000110110111101100100 in base 2. By completing it to 32 bits (from the left), it is equivalent to 64,43,6F,64 in hexadecimal, i.e. the letters 'd,C ,o,d' with the ASCII code.

### How to recognize 32 bit integers? (Identification)

Integers are numbers between -2147483648 and 2147483647, or even 4294967295. Generally, if they encode ASCII characters, then numbers have 10 digits and start with 1, sometimes they have 9 but rarely less.

### Why are 32-bit integers used?

32-bit integers are widely used in computing because they can store a wide range of integer values with sufficient precision for many common applications. Moreover, their size is relatively small, which makes them efficient in terms of memory usage.

### Can numbers larger than 2^31-1 be stored in a 32-bit integer?

No, a 32-bit integer cannot store numbers larger than 2^31-1. If a value greater than this limit is stored in a 32-bit integer, the result will be an overflow error and the value will be truncated.
