Really big numbers

P: 1
I am trying to create a program that calculates the cost of one atom of an element but when I run the code this line...

Expand|Select|Wrap|Line Numbers
  1. decCostPerSingle = decSampleCost / decNumPerSample
gets an error that says "DivideByZeroException was unhandled" I think it may be because my "decNumPerSample" is somewhere around .00000000000000000000000007985 and I think it is rounding down to zero.

How do I fix this problem.

You're very likely to have sussed this out by now, but I think you'll have to settle for Cost per trillion atoms or some other large number.

Just make sure that you multiply up before you divide thus:
(1000000000000 * decSampleCost) / decNumPerSample.
