    Introduction

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

    Enum synopsis

    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. */
    }
