is_float — Finds whether the type of a variable is float

Description

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.

Return Values

Returns TRUE if var is a float, FALSE otherwise.

Examples

Example #1 is_float() example

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)
