18.5. Calculating the
Ceiling of a Numeric Value: ceil() Function
The
ceil() function calculates
the ceiling of a numeric value. The ceiling of a numeric value, say
Value A, means the
smallest integer that is greater than Value A
if Value A is a
floatingpoint number, or Value A
itself if it is an integer. The following WMLScript example can help
you understand what we are talking about:
w
= Float.ceil(10.4); x = Float.ceil(10.5); y =
Float.ceil(10.5); z = Float.ceil(10);
After
the execution of the above script, w and x have the
integral value 11, y has the integral value 10 and z
has the integral value 10.
18.6. Calculating the
Floor of a Numeric Value: floor() Function
The
floor() function calculates
the floor of a numeric value. The floor of a numeric value, say Value
A, means the largest integer
that is smaller than Value A
if Value A is a
floatingpoint number, or Value A
itself if it is an integer. The following WMLScript example can help
you understand what we are talking about:
w
= Float.floor(10.4); x = Float.floor(10.5); y =
Float.floor(10.5); z = Float.floor(10);
After
the execution of the above script, w
and x have the
integral value 10, y
has the integral value 11 and z
has the integral value 10.
