Calculationg the percentage.

I am trying to calculate a percentage.

Code :

double percentage = (numberMatchedEntries / numberEntriesFile1) * 100;

numberMatchedEntries = 20

numberEntriesFile1 = 52

So the output would be about: 38.1%

But from this code:

(numberMatchedEntries / numberEntriesFile1)

I only get 0 back, and not 0,381

I tried using a float too, but it still keeps 0.

And I realy don't know why?

Re: Calculationg the percentage.

What data types are used in the formula? With integer arithmetic: 6/10= 0

using doubles: 6.0/10 = 0.6

Re: Calculationg the percentage.

That would be it.

Those two are int's.

I will change that.

Thanks.
