I'm not sure why there's such surprise/disappointment on Condition('D').
To the best of my knowledge, no SYNTAX conditions return anything for
that. If you wish to have something, you can specify a description on the
RAISE instruction. Other than that, I'm not sure I can be much help here.
I'm not totally surprised that a Rexx version of the calculation might
differ from a C library one in the last digit given that differences in how
the calculations are performed and rounding is done.
