Deltas
Hi All,

I am working my way threw a windows programming book and reach a point i need some info. I have come accross the word delta. What is the definition of that term. (Its not explained in the book, only used. This especially for the lineclipping algo).
I am now at the trapping the mouse section. You can do so by absolute postion (fine, no problems) or by relative deltas?(heh :))
Can someone give me some info on what the latter means....(There is a graphic in the book, but i dont get it)

Cheers,
G'n'R

That's the deffinition it gives in the Jargon File. Meaning 1 is what you're looking for.
I basically means change. eg, from 100 to 160 there's a 60% delta. The symbol is (at least usually) a trinagle.

It's not a 60% delta. /\=60. It's just the change in something.... (v1-v2) where v means value.

I wasn't sure if the % should be there. Thanks for clearing tha out.
BTW, what you did to get the triangle was :cool:
