Ok, this is more of a suggestion of what to do based on my current situation. My situation is that I'm planning on creating a simple calculator and I want 100% accurate calculations. But I discovered that floats only allow 6 digits that makes everything worse when dealing with big rational numbers. SO to deal with this should I create a class that handles rational numbers totally or I continue to use float?

Well the double type is your next data type to try (typically it is around 53 bit mantissa or 15 digits). If that is still too small for your numbers, then yes you will have to go with a custom made class. You can find some already made classes for handling big numbers on the web. Simply do a search.

I hope that answers your question. smile.gif
