New fpprec default value (Was Re: Precision of float and bfloat)



As the precision of ordinary floating point seems to be 14 - 16 decimal
digits, and as many processors now have 64-bit logic as standard, perhaps
32 decimal digits should be default for 'fpprec'.  One could presumably
set the precision to be less that 32 decimal digits if desired.
