### 2.3.1 Operators `bitor, bitxor, bitand`

The integers may be written using hexadecimal notation 0x... for example 0x1f represents 16+15=31 in decimal writting. Integers may also be outputted in hexadecimal notation (click on the red CAS status button and select `Base (Integers)`).
`bitor` is the logical inclusive `or` (bit to bit).
Input :

`bitor(0x12,0x38)`

or :

`bitor(18,56)`

Output :

`58`

because :
`18` is written `0x12` in base 16 or `0b010010` in base 2,
`56` is written `0x38` in base 16 or `0b111000` in base 2,
hence `bitor(18,56)` is `0b111010` in base 2 and so is equal to `58`.
`bitxor` is the logical exclusive `or` (bit to bit).
Input :

`bitxor(0x12,0x38)`

or input :

`bitxor(18,56)`

Output :

`42`

because :
`18` is written `0x12` in base 16 and `0b010010` in base 2,
`56` is written `0x38` in base 16 and `0b111000` in base 2,
`bitxor(18,56)` is written `0b101010` en base 2 and so, is equal to `42`.
`bitand` is the logical `and` (bit to bit).
Input :

`bitand(0x12,0x38)`

or input :

`bitand(18,56)`

Output :

`16`

because :
`18` is written `0x12` in base 16 and `0b010010` in base 2,
`56` is written `0x38` in base 16 and `0b111000` in base 2,
`bitand(18,56)` is written `0b010000` in base 2 and so is equal to `16`.
