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

Println() is deprecated.

 var avgTemp = 66.844322156
  print("average temp. = (round(avgTemp*100)/100)")   // average temp. = 66.84


  //or

 print(NSString(format:"average temp. = %.2f", avgTemp))) // average temp. = 66.84 
 avgTemp = 66.846322156

 print(String(format:"average temp. = %.2f", avgTemp))  // average temp. = 66.85
