Panic in `Repr::into_f64_internal` when calling `Repr::to_f64`

[martinstuder]

DBig::from_str("88888888888888888").unwrap().to_f64(); currently causes the following panic due to a corresponding debug_assert! statement:

panicked at .../.cargo/registry/src/index.crates.io-6f17d22bba15001f/dashu-float-0.4.3/src/convert.rs:617:9:
assertion failed: self.significand.bit_len() <= 53

Is this a bug in the implementation of Repr::to_f64 or what is the recommended way of handling this situation?

I can't reproduce the issue locally, can you explain your system setting? (especially word bit size)

I realized my snippet above was incomplete. I edited to say DBig::from_str("88888888888888888").unwrap().to_f64() - to_f64() is causing the panic. This is happening on Linux 6.13.0-1-MANJARO x86_64.
