Or:
 variable = -variable;
takes less cpu than multiplying by -1.

If you use abs, you'll also have to add -lm to the L_FLAGS in your
makefile (to link to the math library).
Or you could just write your own...
 int my_abs(int a)
 {
   return (a < 0) ? -a : a;
 }

Number * -1

Or

#include <math.h>
Number = abs(Number);

Use the later if you always want it to be positive, the first could
potentially make it go negative if it was positive to begin with...
