math.h and lib for BoostC?

I keep needing things like abs().

I keep needing things like abs().

Never tried BoostC but from what I find with Google (mostly old forum posts) it looks like it might be a roll-your-own situation. Or maybe you could copy some of the headers and libs from libc (do you have Linux?).

int abs(int n) {
    return n > 0 ? n : -n;
}

I was starting to get that idea anyway, judging by the posts on SourceBoost's forums. Shouldn't be that hard to write one anyway.

It's been many many years since I built my own libs for C. I'll have to refresh my foggy old memory.

Good idea. I have almost nothing but Linux. There's windoze on only a few of my too many computers.

Thank you Torben for the abs()! I should have known it would be that simple. My Bresenham line routine now works perfect. Building some nice demos for the site.
