Golden function

The golden function is the upper branch of the hyperbola.

ASP

1. function gold(x)
2.     gold = (x + sqr(x^2 + 4)) / 2
3. end function

PHP

1. function gold($x)
2. {
3.     return ($x + sqrt($x^2 + 4)) / 2;
4. }

Sorry if this is not exciting stuff. I've got some better stuff coming, but I want to clear out some older stuff that has been waiting a while.
