Enum Constant Summary
Enum ConstantsEnum ConstantDescriptionRounding mode to round towards positive infinity.Rounding mode where the values are rounded towards zero.Rounding mode to round towards negative infinity.Rounding mode where values are rounded towards the nearest neighbor.Rounding mode where values are rounded towards the nearest neighbor.Rounding mode where values are rounded towards the nearest neighbor.Rounding mode where the rounding operations throws an ArithmeticException for the case that rounding is necessary, i.e.Rounding mode where positive values are rounded towards positive infinity and negative values towards negative infinity. -
Method Summary
Modifier and TypeMethodDescriptionstatic TRoundingMode
valueOf(int mode)
Converts rounding mode constants from classBigDecimal
intoRoundingMode
values.static TRoundingMode

Enum Constant Details
-
UP
Rounding mode where positive values are rounded towards positive infinity and negative values towards negative infinity.
Rule:x.round().abs() >= x.abs()
-
DOWN
Rounding mode where the values are rounded towards zero.
Rule:x.round().abs() <= x.abs()
-
CEILING
-
FLOOR
-
HALF_UP
Rounding mode where values are rounded towards the nearest neighbor. Ties are broken by rounding up. -
HALF_DOWN
Rounding mode where values are rounded towards the nearest neighbor. Ties are broken by rounding down. -
HALF_EVEN
Rounding mode where values are rounded towards the nearest neighbor. Ties are broken by rounding to the even neighbor. -
UNNECESSARY
Rounding mode where the rounding operations throws an ArithmeticException for the case that rounding is necessary, i.e. for the case that the value cannot be represented exactly.
