gmp_init -- Create GMP number


resource gmp_init ( mixed number)

Creates a GMP number from an integer or string. String representation can be decimal or hexadecimal. In the latter case, the string should start with 0x.

例子 1. Creating GMP number

= gmp_init(123456);
$b = gmp_init("0xFFFFDEBACDFEDF7200");

注: It is not necessary to call this function if you want to use integer or string in place of GMP number in GMP functions, like gmp_add(). Function arguments are automatically converted to GMP numbers, if such conversion is possible and needed, using the same rules as gmp_init().
