Struct ComptimeFloat 

pub struct ComptimeFloat<F: FloatBits>(/* private fields */);

A finite float usable as a comptime kernel parameter.

Plain floats can’t back a Hash/Eq key because NaN breaks reflexivity, which is required for anything used as a kernel cache key (e.g. through KernelId::info). ComptimeFloat closes that gap by comparing and hashing bit patterns instead, after rejecting non-finite input and normalizing -0.0 to 0.0 so numerically equal values always compare equal.

This is only appropriate for values that are genuinely arbitrary floats. If a value is always an exact ratio of two integers (e.g. derived from tensor shapes), prefer Ratio: it is exact and avoids bit-pattern comparisons entirely.
