hexString
hexString
> Functions
Returns a string containing the hexadecimal representation of the integer x, in lowercase, without prefix or leading zeros: hexString(255) returns "ff".
A negative number is written in two's complement over 64 bits, that is 16 hexadecimal digits: hexString(-1) returns "ffffffffffffffff". Big integers are written with their sign.
For the inverse operation, write the number directly with the hexadecimal literal 0xff. Combined with realBits, the function lets you read the internal representation of a real.
Parameters
- x: The integer to write in hexadecimal.
Return
- string: The hexadecimal representation of x.
