I think we will provide math functions (hopefully soon - see NIST proposal

Hackers from Seattle allow spaces but I will rename.

OK, I will explain my 'logical naming scheme', however illogical it may seem

I must protest - I posted my intention to submit a MACROS scheme well
before formal submission - and there was a deafening silence.
It has caused me far more grief having produced the macros file,
and will cause more repetitive strain injury in producing
yet another implementation!
(I'd still like to include the macros in the files -
I don't think our enthusiasm for C++ should not lead us
to exclude a C friendly version on grounds of political incorrectness!)
