I do `import math` to get `gcd` in my program, that's why you got that error.
I still can't get the output from `getPGparameters` assigned to constants of
the same names, to be used later in the program. I thought you could do
assignments like:
const (a, b, c) = tuple(x, y, z)
If tuples aren't the way to do this I don't care, I just want to generate the
parameters and assign them at compile time, to make it easier to use.
