Does anyone know how to display 16 digit numbers without scientific notation?

Now I have this:

dim rt = 4444555544446666
response.write (rt & "<br>")
rt = ((rt-1111333)^.5)/66
response.write (rt & "<br>")
rt = (( (rt*66)^2)+1111333 )
response.write (rt & "<br>")

and I get:

4444555544446666
1010113.63489608
4.44455554444667E+15

I need to diplay '4.44455554444667E+15' without scientific notation which is: '4444555544446666'

Any help greatly appreciated!
