... thinking more about this: currently there is the requirement that:
"The number of digits required after the decimal point (if any) is exactly
the value returned by frac_digits()".

So, if frac_digits() is, say -2?

If I understand well your message, no digits are required after the
decimal_point and we discard the rightmost two digits of the integer part.

These details must really be written *from scratch* in the standard ;)
