How to turn a positive value into a negative

ThunderNox

This question doesn't need much explanation. How do I turn a negative number into a positive one? I know there is the:

but it only turns negative numbers into positive and not the other way. Please Help!

or if you want to be able to keep negative numbers as negative, and turn positive numbers into negative:

You make it so that ANY number minus its absoluted value, (abs) is the same???

just multiple by -1

EDIT: I've edited my earlier post: the last word should have been “negative”.
It's “set to” rather than “change by”. I'm calling the variable “any number” to make clear the variable can be positive or negative to start with. The result will be always be negative, just as the result of “abs” is always positive.

E.g. 7 gets turned into -7, because 0 - abs(7) = 0 - 7 = -7.
And -7 stays as -7 because 0 - abs(-7) = 0 - 7 = -7.

(I've used 0-number but mutiplying by -1 achieves the same thing. 0 - n and n x -1 are both equal to -n.)

You should multiply the number by -1

Oh YES! you are right. for all code and varibles, they differ from 1 to -1

I can't believe I just had to multiply it by -1. I feel so dumb now

Thanks!
