      • toString

        public static final java.lang.String toString​(int roundingMode)
        Returns the name of the rounding mode. Possible values include
        CEILING
        Rounding mode to round towards positive infinity.
        DOWN
        Rounding mode to round towards zero.
        FLOOR
        Rounding mode to round towards negative infinity.
        HALF_DOWN
        Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down.
        HALF_EVEN
        Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor.
        HALF_UP
        Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round up.
        UNNECESSARY
        Rounding mode to assert that the requested operation has an exact result, hence no rounding is necessary.
        UP
        Rounding mode to round away from zero.

      • valueOf

        public static final int valueOf​(java.lang.String name)
        Returns the rounding mode of the specified name.
        Parameters:
        name - the rounding mode's name. Allowed values include:
        CEILING
        Rounding mode to round towards positive infinity.
        DOWN
        Rounding mode to round towards zero.
        FLOOR
        Rounding mode to round towards negative infinity.
        HALF_DOWN
        Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down.
        HALF_EVEN
        Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor.
        HALF_UP
        Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round up.
        UNNECESSARY
        Rounding mode to assert that the requested operation has an exact result, hence no rounding is necessary.
        UP
        Rounding mode to round away from zero.
