LongCalcNetCore 0.5.0

This library, built with and accessible by Visual Studio (2022) and using .Net's BigInteger for the underlying integer math, supplies a variety of math functions and utilities with precisions as large as 2,000,000 base 10 digits. The underlying objects are bf (for 'big float') real values comprised of a BigInteger mantissa and 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 capability of BigInteger. The library also supports algebra on matrices of bf, bd, and bcr objects. This version of LongCalcNetCore depends on .Net 8.
