Usage in Scripts
Let's see what we can do with some of these methods. (By now you can probably figure out these scripts without an explanation, so I won't go into greater detail. Instead, we'll focus on the methods themselves. Still, if a script begins to become complex, I'll stop and explain it. If you need further help, you can always e-mail me.)
Finding the Square Root
An obvious use is to find the square root of a number. Here's a basic script for doing the calculation:
This then would be called by the following, placed in the
body of the document:
Another calculation we could perform would be to round off a number. This script uses the code we wrote previously to find the circumfrence of a circle.
round()method to set the number of decimal places:
The formula for rounding a number to
x decimal points is:
Keep in mind that the format is as follows:
