Decimals
You can also use the class
NSDecimalNumberfor decimal arithmetic.NSDecimalAddNSDecimalCompactNSDecimalCompareNSDecimalCopyNSDecimalDivideNSDecimalIsNotANumberNSDecimalMultiplyNSDecimalMultiplyByPowerOf10NSDecimalNormalizeNSDecimalPowerNSDecimalRoundNSDecimalStringNSDecimalSubtract
Exception Handling
You can find the following macros implemented in
NSException.h. They are obsolete and should not be used. See Exception Programming Topics for information on how to handle exceptions.NS_DURINGNS_ENDHANDLERNS_HANDLERNS_VALUERETURNNS_VOIDRETURN

Uncaught Exception Handlers
Whether there’s an uncaught exception handler function, any uncaught exceptions cause the program to terminate, unless the exception is raised during the posting of a notification.

Managing Zones
Zones are ignored on iOS and 64-bit runtime on OS X. You should not use zones in current development.
