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

Could you make your argument more explicit, please?  Yes, the default 64-bit
floats are 15+ decimal digits; why does that imply that 32 decimal digits
are the appropriate number for fpprec?  Because that is double the number of
decimal digits?
