gmp_init — Create GMP number

### Opis

resource gmp_init ( mixed `$number` [, int `$base` = 0 ] )

Creates a GMP number from an integer or string.

### Parametry

`number`

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

`base`

  The base. Defaults to 0.

  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.

$b = gmp_init("0xFFFFDEBACDFEDF7200");
?>`

### Notatki

> Informacja: 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().
