Namespace: Galaxon.Core.Numbers

Syntax
public static class XLong : objectMethods
Abs(Int64)
Return the absolute value of a long as a ulong. This addresses an issue with long.Abs(), which is that Abs(long.MinValue) can't be expressed as a long, and so wrap-around occurs. Unsigned integer types don't have an Abs() method, so there's no collision.
