math.functions: adding e^-1.
...
This is for calculating e^x-1 for small values more accurately. You can also
call expm1(x) function if you want, and it's available on your platform.
FUNCTION: double expm1 ( double x )

The second case correctly eliminates the bitand but incorrectly assumes
that the item on the stack (which is an integer -- either a fixnum or a
bignum), was converted to a bignum.

The added utility words could be used as a basis to make the other bitwise
interval operations more exact also.
