Const Decimal

const-decimal is a fixed precision decimal backed by an underlying integer. This means it can compute Add/Sub/Mul/Div* operations within it's range without precision loss. This crate was created as there was no pre-existing crate that offered these features for decimal numbers (fixed cannot represent decimals with precision).

This is a fairly simple crate and is mainly intended to serve as a lossless representation of decimal values. While math operations are supported it is not intended to be a general purpose maths library.

* Division can of course truncate like normal division.

Goals

The goals in order of priority are:

• Safety: Panic on over/underflow (even in release).
• Precision: Use integers instead of floats.
• Performance: Use primitive underlying types were possible.
