Summary: round doesn't evaluate 1.0b0

Initial Comment:
round doesn't when the argument is a bigfloat with an integer number value.

examples:

map(round, [1.b0, 1.1b1, 1.11b2, 10.b-1, 100.b-2]);
[round(1.0b0), round(1.1b1), round(1.11b2), round(1.0b0),
round(1.0b0)]

This fails also for floats that are integers.

I think the problem is in simp-round which doesn't handle the case where
the floor and ceiling of the number are the same.
