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]; 

Hope its works for me :D

If not help me any another easy way.
