Introduction
In this article I explain the PHP functions Is_float and Is_double. I will first discuss the Is_float function.
The Is_float() function determines whether the type variable is float or not.
Syntax
Parameter |
|
Var name |
The find variable name is float |
Example
<?php
$var_name=123.23;
if (is_float($var_name))
echo 'Float value.<br>';
else
echo 'Not a Float value.<br>';
var_dump(is_Float(85));
var_dump(is_Float(1e8));
var_dump(is_Float(true));
var_dump(is_Float(array(23.3, 56, 6)));
?>
Output
Next, I will explain the Is_double() function. The is_double() function determines whether the variable is float or not. This function is an alias of float.
Syntax
Parameter |
|
Var name |
The variable being checked. |
Example
<?php
$var_name=123.23;
if (is_double($var_name))
echo 'Double value.<br>';
else
echo 'Not a double value.<br>';
var_dump(is_double(85));
var_dump(is_double(1e8));
var_dump(is_double(true));
var_dump(is_double(array(23.3, 56, 6)));
?>
Output
