gmp_init
(PHP 4 >= 4.0.4, PHP 5, PHP 7)
gmp_init — Create GMP number
Description
Creates a GMP number from an integer or string.
Parameters
-
number -
An integer or a string. The string representation can be decimal, hexadecimal or octal.
-
base -
The base.
The base may vary from 2 to 36. 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, otherwise if the first character is "0", octal is assumed, otherwise decimal is assumed.
Notes
Note:
To use the extended base introduced in PHP 5.3.2, then PHP must be compiled against GMP 4.2.0 or greater.
Examples
Example #1 Creating GMP number
<?php
$a = gmp_init(123456);
$b = gmp_init("0xFFFFDEBACDFEDF7200");
?>
Notes
Note:
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().
