The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding toward positive infinity. In other words, if d is positive, the presence of any fractional component causes d to be rounded to the next highest integer. If d is negative, the rounding operation causes any fractional component of d to be discarded. The operation of this method differs from the Floor(Decimal) method, which supports rounding toward negative infinity.
