Panic occurs when formatting with separator and some format specifier #6212
Description
>>>>> f"{123456:,g}"
thread 'main' panicked at common/src/format.rs:429:18:
Separators only valid for numbers!
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
>>>>> f"{123456:,e}"
thread 'main' panicked at common/src/format.rs:429:18:

But in Python 3.13.5, output is below.
>>> f"{123456:,g}"
'123,456'
>>> f"{123456:,e}"
'1.234560e+05'
I'll fix this bug.
