Example:
NSDecimalNumber *number = [NSDecimalNumber
decimalNumberWithMantissa:2200LL exponent:-2 isNegative:NO];
This results in a decimal number that is represented both
internally, and as a string, as
22
instead of the desired
22.00
Because of the functionality I am trying to achieve, I need to know
the difference between 22 and 22.00, but I can't figure out how to
get NSDecimalNumber to retain the trailing zeros. Does anyone have
advice?
NSDecimalNumber just keeps numerical values, not their history. If two
numbers, _as numbers_, are equal, you should expect the normalized
internal representations to be identical. 22.00 == 22 .
If you need to preserve context, you'll have to keep it yourself in
another data structure (possibly one that wraps an NSDecimalNumber).
