how do I inverse a number?
May 5, 2009
Man, I used to know this but tonight, I just can't seem to get it back... If I have a variabe that is coming in at between 0 and 255 and I need it inverted so that 0 is now 255 and 255 is now 0, what is the equasion? This should be so simple, I just can't seem to remember how to do it!
C'mon math Gods, gimme what you got!!
