Thread: Square prime numbers up to 50 and then round to nearest integer plz help

What I need to do is square all the prime numbers up to 50 and then round to nearest integer. Here is the code I have so far.

public class Test33
{
public static void main (String[] args)
{
int nValues = 50;

OuterLoop:
for(double i = 2; i <= nValues; ++i)
{
for(double j = 2; j < i; ++j)
{
if(i%j == 0)
{
continue OuterLoop;
}
}
System.out.println( Math.sqrt( i ) );
}
}
}




It squares all the primes, but I can't figure out how to round them. I think I need to use Math.round.
ANY help would be appreciated.

To round a floating point number you simply add 0.5 and typecast to int.
If you want to round the variable "someDouble" you can do:

int roundedValue = (int) someDouble + 0.5;
