Question

I have a few double values..35.44, 35.66 . I need to round them, and the result should be as NSNumber. The result should be 35.4 , 35.7. So how to do that ? Once again, the result should be as NSNumber, not NSString !

Answer 1

You could print it to a string and use the format string to clip it to one decimal point.

NSString *stringRepresentation = [NSString stringWithFormat:@"%.1f", myDouble];
NSNumber *number = [NSNumber numberWithDouble:[stringRepresentation doubleValue]];
