Hello, nathanpjones,
Your project is great and I found it from NumSharp source codes.
MS forgot to implement so many functions in decimal class, and you have finished almost the lost ones.
I use your original DecimalMath class to support decimal operation for Math in my Shone.Math () project. I find some methods still absent, such as Sinh, Cosh, Tanh, ASinh, ACosh, ATanh.
By the way, is there a chance to get these functions done in your library to perfectly matching the Math,MathF members in .NET 5?
sinh(x)=(exp(x)-exp(-x))/2
cosh(x)=(exp(x)+exp(-x))/2
tanh(x)=sinh(x)/cosh(x)
Best wishes.
