echo gmp_intval ( "2147483647" ) . "\n" ;
// displays wrong result, above PHP integer limit
echo gmp_intval ( "2147483648" ) . "\n" ;
// displays correct result
echo gmp_strval ( "2147483648" ) . "\n" ;
?>
以上例程会输出:

This function returns a useful result only if the number actually fits the PHP integer (i.e., signed long type). If you want just to print the GMP number, use gmp_strval() .
