Please help me... Translate from c++ to visual basic

can someone help me translate this into visual basic

x = (t_x < pi)? : (x - ( sign( x ) *( 2*pi) ))

function sign(X)
just returns a 1 if x is positive and a -1 if it is negitive

Looks invalid to me, since there's no return value between the ? and :.

Sorry it should be:
x = (t_x < pi)? x: (x - ( sign( x ) *( 2*pi) ))

Well without knowing vb, an easier to convert syntax would be:

Code:

---

if ( !(t_x < pi) )
  x = x - sign(x) * (2 * pi);

---

So it would read:

if t_x not less then pi then x=x-sign(x) *(2*pi)

Correct??

Well just did a search for "vb tutorial" on google, and the first site got me enough info to give you this:

Code:

---

If t_x >= pi Then
  x = x - sign(x) * 2 * pi;

---

Of course I don't have any way of testing it :)

thanks
