No, I meant no y. I want the equation to return a value consistent with a
sawtooth wave as x changes. The way I want to use this function is to create
alternating solid and empty spaces.

It does when the y is removed.

Hmm, you're right, would be +(0..1) regardless of wavelength... but I checked and
the waveform was still what I was looking for.
