Re: Identifying an exact binary representation

It would be nice to have the fp number as a string and then check if
it is possible to represent it exactly in binary, but maybe, for
simplicity, it is not necessary to represent it as a string, maybe it
is possible to investigate the actual binary representation to check
is it was rounded according to IEEE-754 standard or something. I was
primary thinking of some logical function such that isExact(0.25)
returns true and isExact(0.1) returns false. Thanks,

I think that would be isExact('0.25') and isExact('0.1')

On machines with float decimal arithmetic it should return the
appropriate value for that?
