First, you need to turn them into the number (which you're giving in C string syntax here) into an NSString:

char *value1 = "234.3423";
NSString *string1 = [NSString stringWithUTF8String:value1];

Then, simply do this:

double x = [string1 doubleValue];

That's it. If the simple number parsing of NSString is not enough for you, you will need to look into NSNumberFormatter.

double x=[[myArrayList objectAtIndext:1] doubleValue]; double y=[[myArrayList objectAtIndext:2] doubleValue]; Do i do like this . – kiran kumar Oct 25 '10 at 07:13
@kiran kumar: Yes, that's perfectly fine. But note that indexes start with 0. So the first element in the array has index 0, the second 1, etc. – DarkDust Oct 25 '10 at 10:19
