:wave: Hey,

This fixes #4828 by implementing PartialEq in terms of float values for the Ieee{32,64} types.

Previously PartialEq was auto derived. This means that it was implemented in terms of PartialEq in a u32.

This is not correct for floats because NaN != NaN.

PartialOrd was manually implemented in 6d50099816f397c1ff3256d30f742cf041d54e32, but it seems like it was an oversight to leave PartialEq out until now.

The test suite depends on the previous behaviour so we adjust it to keep comparing bits instead of floats.
