Crate bignumbe_rs 

This crate defines a custom medium-precision number type. It can support any base b in the range [0, 65535], and can approximately represent numbers up to b ^ u64::MAX (actually a bit higher than that but the math is complicated). A core goal for this type was that it can implement Copy and as a result it can be used in almost any context a normal unsigned integer would be valid.

Modules

traits

This module contains additional traits I thought may be useful for BigNum usage.

Macros

create_default_base

This macro creates a default Base implementation with a given name and number.

Structs

BigNumBase

This is the main struct for bignumbe-rs.

Binary

This type represents a binary base. It contains more efficient overrides of the Base functions to improve performance.

Decimal

This type represents a decimal base. It contains more efficient overrides of the Base functions to improve performance.

ExpRange

This represents the non-inclusive range of exponents that constitute a valid non-compact significand in the given base. You only need to use this if manually defining a custom base (if performance is non-critical I would recommend using the create_default_base macro).

Hexadecimal

This type represents a hexadecimal base. It contains more efficient overrides of the Base functions to improve performance.

Octal

This type represents an octal base. It contains more efficient overrides of the Base functions to improve performance.

SigRange

This represents the inclusive range of values that constitute a valid non-compact significand in the given base. You only need to use this if manually defining a custom base (if performance is non-critical I would recommend using the create_default_base macro).

Traits

Base

If performance isn’t critical I’d highly recommend the create_default_base macro which creates a base with sensible defaults. The only reason to create a custom implementation is if you find the default implementations’ operations to be a bottleneck. In this case I’d recommend looking at my implementation of the Decimal base as a guide.
