Description
is_float

Return Values

FALSE otherwise.
Examples

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 Notationvar_dump(is_float(true));?>
The above example will output:
bool(true) bool(false) bool(false) bool(true) bool(true) bool(false)
