You can convert integer or double/float value to string by following:

NSString *str = [@(myInt) stringValue];
NSString *str1 = [[NSNumber numberWithFloat:myFloat] stringValue];

After that you can convert string to NSDecimalNumber by many ways. Like:

NSDecimalNumber *number = [NSDecimalNumber decimalNumberWithString:@"100.1"];
NSLog(@"%@", number);
NSDecimalNumber *num = [NSDecimalNumber decimalNumberWithString:@"100.1" locale:NSLocale.currentLocale];
NSLog(@"%@",num);
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterDecimalStyle];
[formatter setLocale:[NSLocale currentLocale]];
NSLog(@"%@", [formatter stringFromNumber:number]);

NSNumberFormatter will help you with the right formatting. Please read apples page for NSDecimalNumber and NSNumberFormatter. NSNumberFormatter contains a section named"Configuring the Format of Currency". I didn't try it, but it seems something that can help you.

Let me know if this helps.. :)
