Hi list

I was wondering what was the most efficient way to process calculations between an NSNumber and an NSDecimalNumber

should I use :

NSNumber *myNormalNumber; NSDecimalNumber *myDecimalNumber; [...] myDecimalNumber = [myDecimalNumber decimalNumberByMultiplyingBy: [NSDecimalNumber decimalNumberWithString:[myNormalNumber stringValue]]];

or

myDecimalNumber = [myDecimalNumber decimalNumberByMultiplyingBy: [NSDecimalNumber decimalNumberWithDecimal:[myNormalNumber decimalValue]]]; (documentation says that decimalValue's value returned isn’t guaranteed to be exact for float and double values)

or should I use parent methods From NSNumber like numberWithFloat:   ?

I use NSDecimalNumber for money related values so my calculations need to be as precise as possible ...


Regards

Pierre Oleo
