I have a workbook that I've inherited and have already made various
revisions to improve it's performance and functionality (what was a 30 minute running time is down to 5). There is one set of items that I haven't changed yet because I'm not sure whether the original programmer didn't have a specific reason for doing it the way he did (taking some of the other changes I've made into consideration, it's a coin toss). There are a *lot* of random numbers generated which are then compared to a column of cell values which are expressed as percentages (yeah, a lookup). Currently, the code coerces the values on *both* sides of this comparison to Integers or Longs before it does the comparison rather than leaving the variables as-is and doing a Single-to-Single comparison. The only reason I can think to do this is that an Integer or Long comparison *might* have some sort of performance edge over a Single comparison that the original programmer knew about and that I don't. However, it seems to me that whatever performance edge there might be (assuming there even is one) would be negated by multiplying 2 variables by 1000 for each comparison. Is there any possible advantage to the existing ConvertedSingleAsLong vs ConvertedSingleAsLong code over changing it to simply read "if SingleA SingleB Then..."? (Figuring it wouldn't hurt to ask before making the change to see what happens...) TIA for any thoughts, -- George Nicholson Remove 'Junk' from return address. |
