Is the test that f is a whole number? f64::EPSILON is 2-53 but it's possible for a positive float to be smaller than that. Try let _ = 2E-54f64.floor(); in your tests.

You're right. Thanks! This should be fixed now

@llogiq I made both changes. I'm not sure about omitting it in tests, so I left that the same for now. What would be the reason for doing that? |

Ah shoot, I messed up with the rebase, didn't I? |
