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
floating-point 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.
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
floating-point 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.
