Protocol Description

The NSDecimalNumberBehaviors protocol declares three methods that control the discretionary aspects of working with NSDecimalNumber(s). The scale and roundingMode methods determine the precision of NSDecimalNumber�s return values and the way in which those values should be rounded to fit that precision. The exceptionDuringOperation:error:leftOperand:rightOperand: method determines the way in which an NSDecimalNumber should handle different calculation errors.

For an example of a class that adopts the NSDecimalNumberBehaviors protocol, see the specification for NSDecimalNumberHandler. —- Apple Documentation
