     BigNum Calculator by Robert Rayment. Does calculations on, up to, 1024 bit numbers (~310 dec & 256 hex digits). Operations on single numbers include shift left/right, roll left/right, Not, Factorial, Squared & Cubed. On two numbers - And, Or, Xor, Eqv, Imp, Div/Mod, Mul, Sub & Add. The full results can be displayed and saved to the clipboard or a file. All calculations are for positive integers only. Make sure to compile the program, particularly for large numbers. Machine code is used for some conversions to speed things up by a few seconds since they take much longer than calculations, principally for 4 digit factorials. For small numbers this has some educational value but very large numbers are just a curiosity, though apparently there is some use in encryption. Zip 27 KB. __________________________________________________ Update: Added view clipboard. __________________________________________________ Update2: Added permutations & combination. Div correction. __________________________________________________ Update3: Minor re-arrangements. __________________________________________________ Update 1st July 2007: Correct FullIntDivision routine.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
