biguint	Infinite precision unsigned integer for substrate runtime.
fixed_point	Decimal Fixed Point implementations for Substrate runtime.
helpers_128bit	Some helper functions to work with 128bit numbers. Note that the functionality provided here is only sensible to use with 128bit numbers because for smaller sizes, you can always rely on assumptions of a bigger type (u128) being available, or simply create a per-thing and use the multiplication implementation provided there.
per_things
rational
traits	Primitive traits for the runtime arithmetic.

Copied from sp-runtime and documented there.

Normalizable	A collection-like object that is made of values of type `T` and can normalize its individual values around a centric point.
ThresholdOrd	Trait for comparing two numbers with an threshold.

Normalize input so that the sum of all elements reaches targeted_sum.
