Precisely.  The question is what to do about potential lexical
representations whose exact value is too large.  float and double
round almost all values quietly so as to get a value in the value
space.  You're just asking for an exception to that rule.  A
perfectly reasonable request for 1.1.  But since it's not backward
compatible, I can't predict whether the WG will consider it
important enough to make the change in 1.1.  In which case, try
for 2.0.
