In https://github.com/peteroupc/Numbers/blob/master/Numbers/PeterO/Numbers/EFloat.cs , you set a default rounding mode for Add and other functions. This is given by EContext.UnlimitedHalfEven . Is this rounding mode the same as I'd get if I did arithmetic on C#'s built-in floats? I want to be able to change between those and EFloat, and know that arithmetic will behave the same way regardless.
Wikipedia on the IEEE 754 rounding rules ( https://en.wikipedia.org/wiki/IEEE_754#Rounding_rules ) says that "Round to nearest, ties to even is the default for binary floating point". By this, it means "rounds to the nearest value; if the number falls midway, it is rounded to the nearest value with an even least significant digit". As far as I can see, that's your PeterO.Numbers.ERounding.HalfEven .
