How to tell if an integer is a multiple of 10 (Xcode)?

How can I tell whether an integer is a multiple of 1开发者_StackOverflow社区0 (i.e. 10, 20, 30, 40, etc) in Objective-C? Thanks.

BOOL isMultipleOfTen = !(someInt % 10);

if((int)myNumber % 10 == 0){
  // it is
}
else {
  // it isn't
}

its pretty much the same for all languages afaik

Purely for @Aurum Aquila's entertainment

disclaimer - DO NOT do this! lol... just a bit of fun

BOOL isDone = NO;
int multiple = 1;
while(!isDone){
  for(int i = 1; i<11; i++){
    if(i*multiple==(int)numberToCheck){
      if(i==10){
        //is multiple
      }
      else{
        //isn't
      }
      isDone = YES;
    }
  }
  multiple++;
}

An entry for Aurum's challenge:

NSString* aString = [NSString stringWithFormat: @"%d", (int) aNumber];
bool isMultipleOf10 = [aString hasSuffix: @"0"];

I was also going to write a version in which I reimplement -stringWithFormat: for integers which would, of course, involve doing lots of explicit n % 10 operations, but I have just lost the will to live.

If the mod result is 0,

try C language code

if(no%10==0){

//number in multiple of 10

}
else{//reminder is not 0

//number is not in multiple of 10
}
