is_float

(PHP 4, PHP 5, PHP 7)
Finds whether the type of a variable is float
bool is_float ( mixed $var )

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:
var

The variable being evaluated.

Returns:

Returns TRUE if var is a float, FALSE otherwise.

Examples:
is_float() example
<?php
if (is_float(27.25)) {
    echo "is float\n";
} else {
    echo "is not float\n";
}
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(false)
bool(false)
bool(true)
bool(true)
bool(false)
