How do u make perl to round a number?

Question

I've made a program in perl and it's kind of a calculator, i want to make it so that it gives u an answer that is rounded. For ex.

1.94444+1=2.95, i want to round it like that

Answer 1

If you wish to round to say, 3 decimal places, you could do something like-

$total = int(($total+0.0005)*1000)/1000

Answer 2

Something like:

printf("%.2f\n", 1.94444 + 1)

Should print out "2.94."

Hope this helps!
