gmp_init — Create GMP number
Creates a GMP number from an integer or string.
num
An integer or a string. The string representation can be decimal, hexadecimal or octal.
base
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.
Um objeto GMP.
Exemplo #1 Creating GMP number
<?php
$a = gmp_init(123456);
$b = gmp_init("0xFFFFDEBACDFEDF7200");
?>
Nota:
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().
