calculated item without if

[bricka]

Hello

I need to implement function:
if xx>32767
then xx = 65535-xx


I'm taking xx with modbus. There must be values between -32767 and 32767. But the controller can't give negative value - only 0...65535
So I need to recalculate it.

Thank's for advice.

You can use conditionals as 1 and 0, so something like x * (x<=32767) + (65535 - x) * (x> 32767) might do it, if a bit ugly.

Works great... just x * (x<=32767) + ( x- 65535) * (x> 32767)
