Thanks for the reminder. Added. |
This PR could use quite a bit of cleanup, especially around hard-coded values and unit tests. In particular, it's probably better to store the hard-coded values using their byte representation as opposed to their decimal one. |

Should we be worried about the cast using as
logic?
I did a fairly big overhaul of the PR in 08531f6:
@celinval This should address some of your comments. |
I'm really sorry, I think you might've misunderstood my comment about the My comment about the |
Not at all. I was planning to make this change before your comment. The reason is that casting a decimal value into a floating-point value can have surprising behavior. For example, this program: println!("{}", u32::MAX);
let f1: f32 = u32::MAX as f32;
let f2: f32 = u32::MAX as f32 + 1.0;
let f3: f32 = (u32::MAX as u128 + 1) as f32;
println!("{:.32}", f1);
println!("{:.32}", f2);
println!("{:.32}", f3); prints:
So casting the decimal value https://www.h-schmidt.net/FloatConverter/IEEE754.html One way to specify a floating-point value unambiguously is to use the byte representation. This is the reason I switched to it. |
I made a few final touches:
@tautschnig @celinval Let me know if you want to take another look. Otherwise, I'll go ahead and merge. |

It's fine by me. Thanks!
