[Chicken-users] numbers egg - (angle y) feedback

[Terrence Brannon]

I tried to re-open the ticket on trac, but was told my submission was potential 
spam.

The (angle) function does not coredump. But it gives a result of 0.0 for an 
argument of 2, which I do not think is correct. The same function in J gives 

-0.416147+0.909297i

Here is a link to the J function, whose name is "r."  ... that's right... "r" 
"dot"

The thing is, most J functions have a monadic and dyadic case. The monadic case 
is relevant in this case and has this description: "The result of r. y is a 
complex number of magnitude 1, whose real and imaginary parts are coordinates 
of the point on the unit circle at an angle of y radians."
