Scientific notation, while supported in Perl 6, is limited to IEEE-754 64bit accuracy so there is some rounding on values using it. Implements a custom "high precision" conversion routine.
Unfortunately, this suffix routine is of limited use for practical everyday purposes. It focuses on handling excessively large and archaic units (googol, greatgross) and completely ignores or makes unusable (due to forcing case insensitivity) many common current ones: c(centi), m(milli), μ(micro). Ah well.
Note: I am blatantly and deliberately ignoring the task guidelines for formatting the output. It has no bearing on the core of the task. If you really, ''really'','' '''REALLY''' ''want to see badly formatted output, uncomment the last line.
