Hi,

This patch has broken our downstream build because of this part: https://github.com/llvm/llvm-project/blob/bc5d5f369d127f8b029a81e4fcd874d4b6454347/libc/src/stdio/printf_core/float_hex_converter.h#L137-L163

The code inside `#ifdef LIBC_MATH_HAS_ASSUME_ROUND_NEAREST_ONLY` was not updated.

Can you please fix it?
