Would something like func (f Function) IsInterpolatedAt(x float64) bool perhaps also cover your use-case? So you could then do if !f.IsInterpolatedAt(x) { // x is not within domain X, f.At(x) is guaranteed to be zero return } // x is within domain X, f.At(x) might be non-zero I actually find it useful that the function is well-defined outside the X domain - this way it can be used wherever a ´f(float)float´ is expected. So personally I'd prefer keeping the signature for At. Open to discussion though :) — You are receiving this because you authored the thread.
