gmp_init - Create GMP number
Code Examples

gmp_init( int|string$num, [int$base = 0] ): GMP

Creates a GMP number from an integer or string.



An integer or a string. The string representation can be decimal, hexadecimal or octal.


The base.

The base may vary from 2 to 62. If base is 0 (default value), the actual base is determined from the leading characters: if the first two characters are 0x or 0X, hexadecimal is assumed, if the first two characters are 0b or 0B, binary is assumed, otherwise if the first character is 0, octal is assumed, otherwise decimal is assumed. 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 usual 10 to 35 while lower-case letter represent 36 to 61.

Return Values

A GMP object.



It is not necessary to call this function in order to use integers or strings in place of GMP numbers in GMP functions (such as with gmp_add). Function arguments are automatically converted to GMP numbers, if such conversion is possible and needed, using the same rules as gmp_init.
