std::time::Duration::from_secs_f64 behavior changed in 1.63.0

• Related release note: https://github.com/rust-lang/rust/blob/stable/RELEASES.md#libraries-3
• Related PR: Improve Duration::try_from_secs_f32/64 accuracy by directly processing exponent and mantissa #90247

Though the PR describes the change is related to improve its truncation better, the changed behavior is rounding up which was down before.

EDIT: The upper changes and issue related to 1.60. It is not related to this issue.

I want to check if this is expected change or regression.

Code

I tried this code:

use std::time::Duration;

fn main() {
    let f: f64 = 1.0020030005;
    let d = Duration::from_secs_f64(f);
    println!("{d:?}");
}

I expected to see this happen: explanation
Until 1.62.1,

1.002003s

Instead, this happened: explanation
In 1.63.0,

1.002003001s

Version it worked on

It most recently worked on: Until 1.62.1

@youknowone -- that PR you linked landed in 1.60, not 1.63?

Oh, I am sorry. I probably didn't check how much I scrolled down from release note.
Then which change would be related?
