The above suggestion will give wrong results for negative numbers.

Real values are already rounded on conversion to Integer (RM 4.6 (33),
viz.:
If the target type is an integer type and the operand type is real, the
result is rounded to the nearest integer (away from zero if exactly
halfway between two integers).

So simply Integer (X) will give correct results for all values of X
within the range of type Integer.

For rounding to, say, the nearest 0.01, one should use an instantiation
of the appropriate generic package from Ada.Text_IO, and use an Aft
value of 2 when calling the Put procedure.  Rounding is done by the
Put procedure.
