The mhyper function seems to be acting strange in that it returns zero when the function is called with variables for the inputs and the last input is greater than about 70. I have attached an example worksheet that illustrates this.
I am using Mathcad 14.0 M020 (14.0.2.5), and a coworker using Mathcad 15 got the same result.
Is there a correction or work around for this?
