How come when I try and square root a Double I get the same answer?
Double VL = 2.0;
VL = Math.sqrt(VL);
System.out.println("VL =" + VL);
Why is the System output:
VL = 2.0

If you run that exact code in JDK 1.5.0 or later, it will print
In earlier versions of
it won't compile.
So there's some difference between the code you're showing us and the code you actually ran -- try putting just this code into an appropriate main() and running it; then try to figure out how your actual code is different.

I agree. Here's the link:

Error : Square root a Float
need help with string to double conversion
How to add main method to this, to check if it works.
