Raising a Numeric
Value to the Power of Another Numeric Value: pow() Function
The
pow() function is used to
raise a numeric value to the power of another numeric value. Its
syntax is:
Float.pow(numeric_value1,
numeric_value2);
The
pow() function returns the result of raising
numeric_value1 to the power of numeric_value2, i.e.
numeric_value1numeric_value2.
If any error occurs, it returns the invalid
value.
Note
that if numeric_value1
is smaller than zero, numeric_value2
must be an integer. If numeric_value1
is zero, numeric_value2
must be zero or greater than zero.
The
following WMLScript example demonstrates how to use the pow()
function:
x
= Float.pow(10, 2); y = Float.pow(10.5, 2.5);
After
the execution of the above script, x
has the floating-point value 100.0 and y
has the floating-point value 357.251.
