GMP::__construct — Create GMP number

### Description

public GMP::__construct(int|string `$num` = 0, int `$base` = 0)

Creates a GMP number from an integer or string.

### Parameters

`num`
  An integer or a string. The string representation can be decimal, hexadecimal, octal, or binary.
`base`
  The base to use for converting a string representation. An explicit base can be between `2` and `62`. For bases up to `36`, case is ignored; upper-case and lower-case letters have the same value. For bases `37` to `62`, upper-case letter represent the values `10` to `35` and lower-case letter represent the values `36` to `61`. If `base` is `0` then the actual base is determined from the leading characters of `num`. If the first two characters are `0x` or `0X`, the string is interpreted as a hexadecimal integer. If the first two characters are `0b` or `0B`, the string is interpreted as a binary integer. If the first two characters are `0o` or `0o`, the string is interpreted as an octal integer. Moreover, if the first character is `0` the string is also interpreted as an octal integer. In all other cases, the string is interpreted as a decimal integer.
