Modulo arithmetic in SignalExpress

[SSteve]

I'm performing arithmetic on the phase output of Tone Generator. I want to keep the output between 0 and 359. Is there any way to do modulo arithmetic in SignalExpress?

There is not a direct modulo function, but you can construct just about anything you want with the Formula step.  For example, to look at an offset sine wave (0 - 1 volt range) modulo 0.5, you can use

 ( ( x0 / 0.5) - floor( x0 / 0.5) )*0.5

There is probably a more efficient formula for doing this, but this gives you the idea.

I figured there was a way but it wasn't coming to me. Your example led me to this:

(phase2-phase1) - (floor((phase2-phase1)/360)*360)

This keeps the result between 0 and 360.

Thanks!
