Sure, division might be a tad more surprising though since most don't do that on an every-day basis. The specific case we had was when a colleague had rewritten

  (a / b) * (c / d) * (e / f)

to

  (a * c * e) / (b * d * f)

as a performance optimization. The result of each division in the original was all roughly one due to how the variables were computed, but the latter was sometimes unstable because the products could produce denomalized numbers.
