Crate bignumbe_rs

Source
Expand description

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.

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

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.
