LongCalc 0.5.33

This library, built with and accessible by Visual Studio (2021) and using Mpir.NET for the underlying integer math and requiring .NetFramework4.5, supplies a variety of math functions and utilities with precisions as large as 2,000,000 base 10 digits when running in x86 mode and much larger in x64 mode. The underlying objects are bf (for 'big float') real values comprised of an mpz_t extended integer part from Mpir.NET and a base 2 exponent, bcr (for complex numbers expressed in the rectangular coordinates) comprised of a bf real part and a bf imaginary part, and bcp (for complex numbers expressed in the polar coordinates) comprised of a bf radius and a bf angle). Functions supported include real and complex versions of: basic arithmetic, trigonometric functions, log and exponential functions, hyperbolic functions and the inverses of all of these, base conversions between bases up to 64, conversions between rectangular and polar coordinates, and some special functions such as Euler, Bernoulli, Gamma, Zeta, and BesselJ. The library also includes a 'bd' (for bigdecimal) object with fractional base 10 digits up to 20686000000. Use of the included Windows app LongCalcDemoApp.exe function assumes that the files LongCalcDemoApp.exe, LongCalc.dll, Mpir.NET.dll, xmpir32.dll, xmpir64.dll reside in a common folder/directory. LongCalc depends on package Mpir.NET and .Net framework 4.5.
