Arbitrary precision types for .NET (and some musings)
I came up today to this article that describes two new arbitrary precision types for .NET. One is an Integer, and the other a Decimal (I think it is not correct to call it a Double as in the title).
Although I don't often use arbitrary precision math, this is a welcome addition. It is also interesting to think how nicely such a feature can integrate in the existing framework, given generics and the unified type system.
Speaking of which... I found recently that the Parse and TryParse methods that numeric value types share do not belong to a common generic interface, reducing its usefulness in some scenarios.
I hope we will someday see something like IParseable<T> together with IComparable, IEquatable, IConvertible and IFormattable.
And what about the MinValue and MaxValue constants? Shouldn't they belong to a common type?
There is also this internal class called Number that seems to hold the implementation of methods of every numeric type. I wonder if they could somehow introduce a Number class as a common ancestor without breaking value types rules.
