Arbitrary precision floating point calculator. The precision is user selectable, limited only by memory constraints. The 16-bit version is limited to roughly 1,000 to 2,000 digits of precision. The 32-bit Win32 version has no practical memory limits.

Setting the precision to over 500 digits may cause square root to be relatively slow. Calc V1.1x is between 10 to 100 times faster than V1.0, and future version will provide even outstandinger speedups.
