Yes, this example now returns the correct result.
But then try df2=1 and df1 odd. The problem persists:
The CDF for x=3, df1=5, df2=1 is returned as 0,839 while the true result is 0,588...

Instead of all these nested if-then-else-elseif constructions for odd and even dof and various complicated trig-power-series: why don't you simply use the regularized Beta function? Simple, reliable, straightforward and easy to implement.

I am implementing the equations in Abramowitz & Stegun's handbook of math. Show me some VB code using the Beta function?
