What it is

Kinogaki's own numeric traits, published under the crates.io name num-traits so the frozen naga and our half resolve to it through [patch.crates-io]. It is not upstream num-traits: it holds only the traits and methods those two crates call, implemented for the primitive types with std's float functions.

The conversions follow num-traits' documented rules, which naga's constant evaluator depends on:

float to integer truncates toward zero and is None when the truncated value does not fit (or the float is NaN or infinite);
integer to float rounds to nearest, ties to even (Rust's as);
float to float is Rust's as (finite values may overflow to infinity).

Depends on

None.

Third-party

None.
