CG shader functions behaving oddly on iPad Pro

I've noticed a few maths functions produce unexpected results only on iPad Pro. The two main ones I've noticed so far are pow and step, which seem to produce erroneous values. I've tested the exact same functions on other ipads (Air, mini2, 4) and they work fine. Anyone have any idea what's going on here? Obviously I can work around these issues but it's not ideal.
