10.4 Decimals

These functions are used to perform decimal arithmetic with NSDecimal type structs. The Foundation class NSDecimalNumber may also be used for decimal arithmetic.

NSDecimalAdd

NSCalculationError NSDecimalAdd(NSDecimal *result, const NSDecimal *leftOperand, const NSDecimal *rightOperand, NSRoundingMode roundingMode)

NSDecimalCompact

void NSDecimalCompact(NSDecimal *number)

NSDecimalCompare

NSComparisonResult NSDecimalCompare(const NSDecimal *leftOperand, const NSDecimal *rightOperand)

NSDecimalCopy

void NSDecimalCopy(NSDecimal *destination, const NSDecimal *source)

NSDecimalDivide

NSCalculationError NSDecimalDivide(NSDecimal *result, const NSDecimal *leftOperand, const NSDecimal *rightOperand, NSRoundingMode roundingMode)

NSDecimalMultiply

NSCalculationError NSDecimalMultiply(NSDecimal *result, const NSDecimal *leftOperand, const NSDecimal *rightOperand, NSRoundingMode roundingMode)

NSDecimalMultiplyByPowerOf10

NSCalculationError NSDecimalMultiplyByPowerOf10(NSDecimal *result, const NSDecimal *number, short power, NSRoundingMode roundingMode)

NSDecimalNormalize

NSCalculationError NSDecimalNormalize(NSDecimal *number1, NSDecimal *number2, NSRoundingMode roundingMode)

NSDecimalPower

NSCalculationError NSDecimalPower(NSDecimal *result, const NSDecimal *number, unsigned power, NSRoundingMode roundingMode)

NSDecimalRound

void NSDecimalRound(NSDecimal *result, const NSDecimal *number, int scale, NSRoundingMode roundingMode)

NSDecimalString

NSString *NSDecimalString(const NSDecimal *dcm, NSDictionary *locale)

NSDecimalSubtract
