Class Overview
Specifies the rounding behavior for operations whose results cannot be
represented exactly.
Summary

CEILING
Rounding mode to round towards positive infinity. For positive values
this rounding mode behaves as UP, for negative values as
DOWN.
Rule: x.round() >= x
public

final
RoundingMode
DOWN
Rounding mode where the values are rounded towards zero.
Rule: x.round().abs() <= x.abs()
public
static
final
RoundingMode
FLOOR
Rounding mode to round towards negative infinity. For positive values
this rounding mode behaves as DOWN, for negative values as
UP.
Rule: x.round() <= x

HALF_DOWN
Rounding mode where values are rounded towards the nearest neighbor. Ties
are broken by rounding down.
public

final
RoundingMode
HALF_EVEN
Rounding mode where values are rounded towards the nearest neighbor. Ties
are broken by rounding to the even neighbor.
