42 - Integers

int / uint: Signed and unsigned integers of various sizes. Keywords uint8 to uint256 in steps of 8 (unsigned of 8 up to 256 bits) and int8 to int256. uint and int are aliases for uint256 and int256, respectively.

Operators are: 

1. Comparisons: <=, <, ==, !=, >=, > (evaluate to bool)

2. Bit operators: &, |, ^ (bitwise exclusive or), ~ (bitwise negation)

3. Shift operators:

   • << (left shift)
   • >> (right shift)

4. Arithmetic operators: +, -, unary - (only for signed integers), *, /, % (modulo), ** (exponentiation)
