floating point number imprecision while iterating

Question

I have a function that computes a point in 3d spaced based on a value in range [0, 1]. The problem I\'m facing is, that a binary floating-point number canno

Answer 1

When comparing floating point numbers you should check if they are close enough not exactly equal, for the reasons mentioned in other answers, something like:

#define EPSILON 0.000001f
#define FEQUAL(a,b) (fabs((a) - (b)) < EPSILON)
