The RoundingMode Enum

Giriş

The RoundingMode enum is used to specify how rounding should be performed for round(), bcround(), and BCMath::round().

enum RoundingMode
{

case HalfAwayFromZero ;
/** Round to the nearest integer. If the decimal part is 5, round to the integer with the larger absolute value. */

case HalfTowardsZero ;
/** Round to the nearest integer. If the decimal part is 5, round to the integer with the smaller absolute value. */

case HalfEven ;
/** Round to the nearest integer. If the decimal part is 5, round to the even integer. */

case HalfOdd ;
/** Round to the nearest integer. If the decimal part is 5, round to the odd integer. */

case TowardsZero ;
/** Round to the nearest integer with a smaller or equal absolute value. */

case AwayFromZero ;
/** Round to the nearest integer with a greater or equal absolute value. */

case NegativeInfinity ;
/** Round to the largest integer that is smaller or equal. */

case PositiveInfinity ;
/** Round to the smallest integer that is greater or equal. */
