    (PHP 8)

    fdiv — Divides two numbers, according to IEEE 754

    Description

    fdiv(float $num1, float $num2): float

    Returns the floating point result of dividing the num1 by the num2. If the num2 is zero, then one of INF, -INF, or NAN will be returned.

    Note that in comparisons, 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 of num1/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)
    ?>
