    is_float — Finds whether the type of a variable is float

    Description

    is_float(mixed $value): bool

    Finds whether the type of the given variable is float.

    Note:

    To test if a variable is a number or a numeric string (such as form input, which is always a string), you must use is_numeric().

    Parameters

    value

    The variable being evaluated.

    Return Values

    Returns true if value is a float, false otherwise.

    Examples

    Example #1 is_float() example

    <?php

    var_dump    (is_float(27.25));
    var_dump(is_float('abc'));
    var_dump(is_float(23));
    var_dump(is_float(23.5));
    var_dump(is_float(1e7)); //Scientific Notation
    var_dump(is_float(true));
    ?>

    The above example will output:

    bool(true)
bool(false)
bool(false)
bool(true)
bool(true)
bool(false)
