enum NppRoundMode

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. Also see Rounding Modes.

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.

Enumerator
NPP_RND_NEAR	Round to the nearest even integer. All fractional numbers are rounded to their nearest integer. The ambiguous cases (i.e. <integer>.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	Alias name for NPP_RND_NEAR.
NPP_RND_FINANCIAL	Round according to financial rule. All fractional numbers are rounded to their nearest integer. The ambiguous cases (i.e. <integer>.5) are rounded away from zero. E.g. roundFinancial(0.4) = 0 roundFinancial(0.5) = 1 roundFinancial(-1.5) = -2
NPP_ROUND_NEAREST_TIES_AWAY_FROM_ZERO	Alias name for NPP_RND_FINANCIAL.
NPP_RND_ZERO	Round towards zero (truncation). All fractional numbers of the form <integer>.<decimals> are truncated to <integer>. roundZero(1.5) = 1 roundZero(1.9) = 1 roundZero(-2.5) = -2
NPP_ROUND_TOWARD_ZERO	Alias name for NPP_RND_ZERO.

enum NppStatus

Almost all NPP function return error-status information using these return codes. Negative return codes indicate errors, positive return codes indicate warnings, a return code of 0 indicates success.
