Arduino & Algebra

Will Arduino do Algebra calculations including exponent math functions?

Here is the example:

Pw = (RH/100)EXP(17.863-9621/(T+460))
W= 70000.62198/(29.92/Pw-1)

where RH= relative humidity % and T= Temperature (dry bulb)

This is to calculate Grains Per Pound of Air. Moisture content in air.

No, Arduino does not do algebra (symbolic manipulation).

But those formulas can be evaluated if you define all the variables as floats (Pw, RH, T, W) and provide reasonable values for the primary variables (RH and T). The name of the exponential function is exp.

Defining the variables I understand because I would be putting in temp and humidity from a BME280. I did look at exponential function and the meaning of symbolic manipulation. So it looks like it can be calculated.

I thought it was Algebra, but that's what I get for thinking. Been a long time ago for math class. Just have to learn some of it all over again.

THANKS!

Algebra allows you to do and say things like this:

if A=B*C, then B=A/C.

Ok! Got it! Sorry I updated my previous post. I was woried that Arduino would not be able to pull this of but that's great that I can do it.

Thanks!
