I am trying to trim zeros after a decimal point as below but it's not giving desired result.
trig = [currentVal doubleValue];
trig = trig/100;
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
display.text = [formatter stringFromNumber:[NSNumber numberWithDouble:trig]];
From the documentation, it looks like
setFractionDigits: is only for converting the other way.
The best thing to do is probably to convert your number to an integer before formatting it e.g.
double converted = round(trig); // man round for docs
You can use also the formatting functions of
NSString, but then you will lose all the localisation advantages you get with
