### Is your feature request related to a problem or challenge? Right now, `parse_decimal_mantissa` loops over the digits of the input. Digits that appear before the decimal point are handled differently than those after the decimal point; some profiling suggests that doing this branch inside the loop hurts codegen. It would be pretty easy to instead refactor the code to do two loops: scan for digits until the decimal point is seen, and then scan post-decimal-point digits until end-of-string is seen. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
