Question

I have 53.025709438664 in string when I do [string_variable doubleValue], I get 53.025709.
I use NSLog(@"%f") to print it.

How I can get full precision value ?

Answer 1

Please have a look at the format specifiers provided in Apple doc.

You cannot get all the digits after decimal point.

Edit:
If you know exact number of digits after decimal, then we could use something as follows

NSString *s  = @" 53.025709438664";
double d = [s doubleValue];
NSLog(@"%.12f",d);
