Wanted mathematical functions?

I am thinking sin/cos/tan and then a x^y type function... Perhaps a natural log?

I think the most useful would be the x^y because when making a Taylor Series, it can get tedious to do x*x*x*x*x*x*x*x*x*x*C type things.

Put up requests and I will think about it.

Again this is only for the MDX software, not Version 2.

absolute value, square root (although it may be redudant), and I like the ones above as well.

In the world of controls, this one is kind of math:

how about delay on and delay off timers? I would be ok if the nemeric input to the timer was not seconds, but a multiplier to the timer object,

i.e.
my timer is at the default 50.
I want to create a root function that takes a temperature variable and compares it to a constant, if it is greater than the constant for 5 seconds. then do something (like set a boolean variable somewhere else to 1).

So, if 50 is 50ms, then 5000/50 is 100, so that would be the timer input I would use.

Then again, if you make it so that it to 5seconds, looked at the timer value and did that behind the scene, it would be more user friendly.

Time intervals may need to be defined for deriviative/integral as well.

introduction of "time" to modules would also allow for filtering, and would allow for a possibly useful Totalizer (resetable).

You can actually access all history values of an analogue input anytime in the logic... Is that you meant? So you can get now (t=0) and t-1, t-2, t-3, t-4,... t-n where n is the number of history points an analogue input stores.
