Apparently there were concerns about the correctness of the result on some
message board. To be clear: This is a *benchmark* designed to execute the
same code for float, cdecimal and decimal.

The *original* algorithm from the decimal docs uses a higher intermediate
context precision. Since floats do not have such a context, this step was
deliberately dropped from the benchmark.
