Windows requirements

API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Fields

None	0	Do not use.
RoundAwayFromZero	4	Round away from zero. This is the equivalent of RoundUp if the input is positive, or RoundDown if the input is negative.
RoundDown	1	Round towards negative infinity. (Return the largest integer, increment, or significant digit which does not exceed the input.)
RoundHalfAwayFromZero	8	Round to the integer, increment, or significant digit that is closest to the input. If the input is exactly halfway between the possible outputs, this is the equivalent of RoundAwayFromZero.
RoundHalfDown	5	Round to the integer, increment, or significant digit that is closest to the input. If the input is exactly halfway between the possible outputs, this is the equivalent of RoundDown.
RoundHalfToEven	9	Round to the integer, increment, or significant digit that is closest to the input. If the input is exactly halfway between the possible outputs, round to the nearest even output.
RoundHalfToOdd	10	Round to the integer, increment, or significant digit that is closest to the input. If the input is exactly halfway between the possible outputs, round to the nearest odd output.
RoundHalfTowardsZero	7	Round to the integer, increment, or significant digit that is closest to the input. If the input is exactly halfway between the possible outputs, this is the equivalent of RoundTowardsZero.
RoundHalfUp	6	Round to the integer, increment, or significant digit that is closest to the input. If the input is exactly halfway between the possible outputs, this is the equivalent of RoundUp.
RoundTowardsZero	3	Round towards zero. This is the equivalent of RoundDown if the input is positive, or RoundUp if the input is negative.
RoundUp	2	Round towards infinity. (Return the smallest integer, increment, or significant digit which is not less than the input.)
