Remarks

The DB2RoundingMode enumeration is used when populating a DB2DecimalFloat instance using the DB2DecimalFloat.Parse method.

Table 1. Members
Member	Description
Ceiling	Round toward positive infinity. If all of the discarded digits are zero or if the sign is negative, the result is unchanged. Otherwise, the result coefficient should be incremented by 1 (rounded up).
Down	Round toward 0 (truncation). The discarded digits are ignored.
Floor	Round toward negative infinity. If all of the discarded digits are zero or if the sign is positive, the result is unchanged. Otherwise, the sign is negative and the result coefficient should be incremented by 1 (rounded up).
HalfDown	Round to nearest; if equidistant, round down. If the discarded digits represent greater than half (0.5) of the value of a one in the next left position, then the result coefficient should be incremented by 1 (rounded up). Otherwise (if the discarded digits are 0.5 or less), the discarded digits are ignored.
HalfEven	Round to nearest; if equidistant, round so that the final digit is even. If the discarded digits represent greater than half (0.5) the value of a one in the next left position, then the result coefficient should be incremented by 1 (rounded up). If they represent less than half, then the result coefficient is not adjusted (that is, the discarded digits are ignored). Otherwise (if they represent exactly half), the result coefficient is unaltered if its rightmost digit is even, or incremented by 1 (rounded up) if its rightmost digit is odd (to make an even digit).
HalfUp	Round to nearest; if equidistant, round up. If the discarded digits represent greater than or equal to half (0.5) of the value of a one in the next left position then the result coefficient should be incremented by 1 (rounded up). Otherwise, the discarded digits are ignored.
Up	Round away from 0. If all of the discarded digits are zero the result is unchanged. Otherwise, the result coefficient should be incremented by 1 (rounded up).
