Check if NSNumber has trailing .00 digits or not

I have a method that creates a money style string from an NSNumber. ``` + (NSString *)formatShortPayment: (NSNumber *)payment { if (![payment isEqual: [NSNull null]]) { // Set locale to GB NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_GB"]; NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; [formatter setLocale: locale]; [formatter setNumberStyle: NSNumberFormatterCurrencyStyle]; // If the payment is 1000 or over, get rid of fraction numbers if ([payment doubleValue] >= 1000.0) { [formatter setMaximumFractionDigits: 0]; payment = [NSNumber numberWithFloat:([payment floatValue] / 1000)]; } else { // Here's where I want to check if the value ends with .00 or not } // Return clean number return [formatter stringFromNumber: payment]; } return nil; } ``` This works great, but if the value is < 1000.0 I'd like to check what the trailing digits are and remove them if they equal .00. For example: 25.00 => 25 13.29 => 13.29 I'm not sure how best to accomplish this. Any suggestions?
