FWIW, mathworld (the usual place for mathematical definitions) has a
cruddy definition of monotone function too: it assumes the function is
a differentiable function of the reals. Fer 'eavens sake, you don't
even need a total order...

This is monotonic increasing, of course.
Lets try that again:
f monotonic <=> ((x>=y => f(x) >= f(y) for all x,y)
OR (x>=y => f(x) <= f(y) for all x,y))
Cheers,
M.
