"Max[f[Range[0, 1, .001]]]

does not yield the desired result."

You haven't told us what the desired result IS, but I'm sure you're right.

Here's one possibility:

f[x_] = Piecewise[{{1, x < 1}, {2, x > 1}}];
Max[f /@ Range[0, 1, .001]]

1

Note that we have

f[1]

0

since 1 is neither < 1 nor > 1.
