I have an interface giving me numbers like this 0000000012345,78
So i figured out how to make a number out of them. But I need to calculate with that number and what I actually need is a decimal number.
NSNumberFormatter *fmtn = [[NSNumberFormatter alloc] init];
[fmtn setFormatterBehavior:NSNumberFormatterBehavior10_4];
[fmtn setNumberStyle:NSNumberFormatterDecimalStyle];
[fmtn setDecimalSeparator:@","];
NSNumber *test = [fmtn numberFromString:@"0000000012345,78"];
How can I make my NSNumber to a NSDecimalNumber?
EDIT: This is the code I ended up with:
NSDictionary *localeDict = [NSDictionary dictionaryWithObject:@"," forKey:@"NSDecimalSeparator"];
NSDecimalNumber *test = [[NSDecimalNumber alloc] initWithString:@"00000000012345,78" locale:localeDict];
How to put together the locale dictionary could not be described as "well documented" and it took me some googling to find an example.
This one also worked:
NSLocale *deLoc = [[NSLocale alloc] initWithLocaleIdentifier:@"de"];
NSDecimalNumber *testd = [NSDecimalNumber decimalNumberWithString:@"00000000012345,78" locale:deLoc];
To convert an NSNumber
to NSDecimalNumber
, wouldn't it make more sense to avoid the character representation altogether with this code?
NSNumber* source = ...;
NSDecimalNumber* result = [NSDecimalNumber decimalNumberWithDecimal:[source decimalValue]];
