I'm trying to work on a dataset that has its primary numbers saved as floats in string format. I'd like to work with them as integers with an implied decimal to the hundredth. The problem is that the current precision is variable. For instance, some numbers have 4 decimal places while others have 2, etc. (10.7435 vs 1074.35)... all numbers are of fixed length.
I have some ideas of how to do this, but I'm wondering if there's a better way. My current way is to brute force search where the decimal is by slicing and then cutoff the extraneous numbers, however, it would be nice to stay away from a bunch of if then's.
Does anyone have any ideas on how to do this more efficiently?
If you can live with a small possibility of error, then:
int(float(numIn) * 100.0)
should do the trick.
If you can't, and the numbers are guaranteed to have a decimal point, this (untested) could do what you want:
aList = numIn.split(".")
result int(aList[0]) * 100 + int(aList[1][:2])HTH

Many Thanks, Lorn
