Seems unlikely, consider the vagaries of this with binary representation
and decimal conceptualization.

Printf() was a good suggestion.  Look at sprintf to print to a string,
and strtod to convert it back.  

WARNING:  This should do the trick, but again the result is not 
as straight-forward as you _might_ think.

Hope this helps.
