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

Not Swift but I'm sure you get the idea.

pow10np = pow(10,num_places);
val = round(val*pow10np) / pow10np;
