load(functs) gives access to the function gd(x), the gudermannian. It is constructed wrongly, it should be 2 * atan(%e^x) - %pi/2, not as given below in documentation which is also wrong.

Function: gd (x)

Returns the Gudermannian function 2 * atan(%e^x - %pi/2).

To use this function write first load(functs).

    suggested fix applied (functs.mac, CVS revision 1.9); also fixed user documentation.

    Thanks for the bug report.
