In true Forth style, ANS abandoned the ready-to-use functions originally
planned and supplied REPRESENT so you can DIY.  The result of which
functions like (F.) keep on being reinvented with varying degrees of
competence.  What's not to like :)

The source for the f/p is provided.  VFX >FLOAT uses >NUMBER for the
conversion which limits the mantissa to 19 digits on a 32-bit forth.  Convert
more and it silently fails.  Win32F faced a similar issue with the x87 FBLD
instruction which accepts only 18 digits.  IIUC their solution is to FBLD the
first 18 digits of the mantissa which returns a real, then manually adjust for
the remaining digits.
