RE: Multiply Versus Divide

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

Bill,

This is probably one of those cases where the effort exceeds the benefit.
Unless you're running this calculation on a massive scale, you'd probably be
hard-pressed to justify a x nanosecond improvement in performance.  

I fall into the "make it maintainable" camp that would prefer legibility to
performance.

Does anyone else, besides me, try to use multiplication wherever they can
instead of division?  Is it still a performance consideration when dealing
with a "large" number of calculations?

WorkDate = (((NbrDate * .0001) - 3) * 10000) + 101
