    (javascript) getting the negative version of a positive number. **Resolved**

    OK, I know there is a term for this but I never payed attention in school and I'm sure if I knew the term I could look it up myself but since I didnt I have to ask. I need the negative version of a positive number.... for example I have 500 but I need -500. I can easily do it this way (500 - 500 - 500) but I know that is poor, and am sure javascript has a function to do this.
    Thanks

    Found out that I can just add the - to the front of the variable and it will work.
    -var1

    Way back when I was learning C++, this is what we did. It is a very mystical and complicated procedure:
    Code:
    myInt = myInt * -1
    If you wanted to make sure you weren't changing a negative to a positive, you could call the absolute value function/operator, and then the multiplication.
