Name

ceil()

Synopsis

    float ceil ( float num )

The ceil() function takes a floating-point number as its only parameter and rounds it to the nearest integer above its current value. If you provide an integer, nothing will happen. For example:

    $number = ceil(11.9); // 12
    $number = ceil(11.1); // 12
    $number = ceil(11); // 11
