GMP::__construct
Create GMP number
Description
public GMP::__construct(intstring $num = 0, int $base = 0)
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.
