Sometimes I have a feeling that I should be avoiding division in all cases to begin with, but then, there are cases where it seems all too indispensable. Especially when a value is a measure with an ignored error, division close to zero is almost meaningless. Is it a realistic goal to try and avoid division in the first place? I don't remember my numerical computing course well enough
