PHP: fdiv - Manual (original) (raw)

(PHP 8)

fdiv — Divides two numbers, according to IEEE 754

Description

Returns the floating point result of dividing thenum1 by the num2. If the num2 is zero, then one of [INF](math.constants.php#constant.inf), -[INF](math.constants.php#constant.inf), or [NAN](math.constants.php#constant.nan) will be returned.

Note that in comparisons, [NAN](math.constants.php#constant.nan) will never be equal (==) or identical (===) to any value, including itself.

Parameters

num1

The dividend (numerator)

num2

The divisor

Return Values

The floating point result ofnum1/num2

Examples

Example #1 Using fdiv()

<?php var_dump(fdiv(5.7, 1.3)); // float(4.384615384615385) var_dump(fdiv(4, 2)); // float(2) var_dump(fdiv(1.0, 0.0)); // float(INF) var_dump(fdiv(-1.0, 0.0)); // float(-INF) var_dump(fdiv(0.0, 0.0)); // float(NAN) ?>
