The manual [ https://gmplib.org/manual/Floating_002dpoint-Functions.html ]
reads:
"[...] decimal fractions like 0.1 cannot be represented exactly. [...]
This makes [float and mpf_t] highly unsuitable for calculations involving
money or other values that should be exact decimal fractions. (Suitably
scaled integers, or perhaps rationals, are better choices.)"

The "rationals" way was discussed recently on our lists:

(and previous messages.)

Thank you for using and testing it,
