Error-free transformations of two term sums

Required Methods§

Sum transformation

Transforms a sum a + b into the pair (x, y) where

x = fl(a + b)

is the sum of a and b with floating point rounding applied and

y = a + b - x

is the remainder of the addition.

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
