18.4. Calculating the
Square Root of a Numeric Value: sqrt() Function
The
sqrt() function calculates
the square root of a numeric value. If any error occurs, it returns
invalid. The
following WMLScript example demonstrates the use of sqrt():
x
= Float.sqrt(100); y = Float.sqrt(25); z = Float.sqrt(14);
After
the execution of the above script, x
has the floating-point value 10.0, y
has the floating-point value 5.0 and z
has the floating-point value 3.74166.
