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

Everything about the format of a number as a string can be adjusted using a NSNumberFormatter:

let nf = NSNumberFormatter()
nf.numberStyle = NSNumberFormatterStyle.DecimalStyle
nf.maximumFractionDigits = 2
println(nf.stringFromNumber(0.33333)) // prints 0.33

You can escape quotes with a backslash

println("\"God is dead\" -Nietzsche")
