Rounding a double value to x number of decimal places in swift

Question

Can anyone tell me how to round a double value to x number of decimal places in Swift?

I have:

var totalWorkTimeInHours = (totalWorkTime/60/60)
         


        

Answer 1

I would use

print(String(format: "%.3f", totalWorkTimeInHours))

and change .3f to any number of decimal numbers you need
