Does C# have an Unsigned Double?

Question

I need to use an unsigned double but it turns out C# does not provide such a type.

Does anyone know why?

Answer 1

Floating point numbers are simply the implementation of the IEEE 754 spec. There is no such thing as an unsigned double there as far as i know.

Why do you need an unsigned floating point number?
