MathM
C# math library for supporting System.Decimal floating-point numberss.
The .NET Decimal data type is included in .NET, but is often overlooked for scientific calculations. It's high precision and exact up to 28 decimal places and it's available in any .NET environment.
You might be in a situation where you just need a lot more precision than Double can provide. I used Decimal for calculating locations in space for CNC manufacturing and pick and place control. I've found the increased precision of Decimal reduces overall errors throughout the set of calculations and it also improves the odds of reversing the calculations if necessary for debugging. In that case it ends up being a kind of oversampling.
Unfortunately, a lot of the usual number functionality is not provided for .NET. For example, you can't calculate a square root or even perform exponentiation. You can cast to Double for these operations, but you can end up with a significant loss of precision.
