Code for Ending Test

Here is the code for ending the loop when |n/x*x - 1| < 0.00001.

## $f0  ---  n
## $f1  ---  1.0
## $f2  ---  2.0
## $f3  ---  x  : current approx.
## $f4  ---  x' : next approx.
## $f8  ---  temp
## $f10 ---  small value

        mul.s   $f8,$f3,$f3         # x^2
        div.s   $f8,$f0,$f8         # n/x^2
        sub.s   $f8,$f8,$f1         # n/x^2 - 1.0
        abs.s   $f8,$f8             # |n/x^2 - 1.0|
        c.lt.s  $f8,$f10            # |x^2 - n| < small ?
        bc1t    done                # yes: done
  
        j       loop
        
done:
