View Full Version : Displaying float with only 2 decimal places?

Is it possible to display a float variable only out to the 2nd decimal place (hundredths place)?

Look at the documentation for NSString stringWithFormat (http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/clm/NSString/stringWithFormat:). You can specify the number of decimal places easily.

Thanks for your help.

Incase anyone else finds this in a search, the way to do it is to use %.2f in the stringWithFormat: method.

Yup - that's a winner...

(more fodder for searches)

The String Programming Guide for Cocoa section on String Format Specifiers (https://developer.apple.com/iphone/library/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html) describes all of the options, but for things like the ".2" part you need to see the referenced IEEE printf() (http://www.opengroup.org/onlinepubs/009695399/functions/printf.html) description.
