How to use println in Swift to format number

Question

When logging-out a float in Objective-C you can do the following to limit your output to only 2 decimal places:

float avgTemp = 66.844322156
NSLog (@\"averag         


        

Answer 1

Here's the shortest solution I found thus far:

let avgTemp = 66.844322156
println(NSString(format:"%.2f", avgTemp))

Its like the swift version of NSString's stringWithFormat
