File Calc Binary Calculator for Enormous Numbers

Files on computers are stored in binary numbers 1's and 0's. Basically a file on a computer is just a big number. File Calc allows you to use this idea to do basic math on the large numbers that are computer files.

Most calculators are built using 32 or 64 bit number limitations. File Calc was written as an experiment to lift that upper bound. By working off computer files enormous numbers that stretch into megabytes can be used. Very large numbers can be calculated without the loss of data given by scientific notation.

.Net 4.0 Beta Framework:  File Calc was originally written in 2001 to test various encryption ideas. While functional it was always a dog performance wise. As times change so does the technology available. New in the .Net 4 Beta Framework is the BigInteger data type. BigInteger also allows for mathematical operations to be performed on huge numbers. Curious as to how the two might compare File Calc was dug out of mothballs and given a WPF face lift. The results were not even close. The .Net 4.0 Beta version of File Calc is dramatically faster. Microsoft has a real winner on their hands with the new BigInteger data type.
