Class NppRoundMode

java.lang.Object

jcuda.jnpp.NppRoundMode

public class NppRoundMode
extends java.lang.Object

Rounding modes. The enumerated rounding modes are used by a large number of NPP primitives to allow the user to specify the method by which fractional values are converted to integer values. For NPP release 5.5 new names for the three rounding modes are introduced that are based on the naming conventions for rounding modes set forth in the IEEE-754 floating-point standard. Developers are encouraged to use the new, longer names to be future proof as the legacy names will be deprecated in subsequent NPP releases.

Field Detail

NPP_RND_NEAR

public static final int NPP_RND_NEAR

Round to the nearest even integer. All fractional numbers are rounded to their nearest integer. The ambiguous cases (i.e. \.5) are rounded to the closest even integer. E.g. - roundNear(0.5) = 0 - roundNear(0.6) = 1 - roundNear(1.5) = 2 - roundNear(-1.5) = -2

NPP_ROUND_NEAREST_TIES_TO_EVEN

public static final int NPP_ROUND_NEAREST_TIES_TO_EVEN

Constant Field Values

NPP_RND_FINANCIAL

public static final int NPP_RND_FINANCIAL

Round according to financial rule. All fractional numbers are rounded to their nearest integer. The ambiguous cases (i.e. \.5) are rounded away from zero. E.g. - roundFinancial(0.4) = 0 - roundFinancial(0.5) = 1 - roundFinancial(-1.5) = -2

Constant Field Values

NPP_RND_ZERO

public static final int NPP_RND_ZERO

Round towards zero (truncation). All fractional numbers of the form \.\ are truncated to \. - roundZero(1.5) = 1 - roundZero(1.9) = 1 - roundZero(-2.5) = -2
