Hi!

I got some problems with math operations in my sketch:

Polynom and divisions does not work.

I’ve got this polynom 6th grade which does not work:

OelTemp = 2*pow(10, -18)*pow(Oelu2, 6)

- 2*pow(10, -14)*pow(Oelu2, 5)

- 1*pow(10, -10)*pow(Oelu2, 4)

- 3*pow(10, -7) *pow(Oelu2, 3)

- 0.0003 *pow(Oelu2, 2)

- 0.2793* Oelu2

- 160.81;

even this does not work val = val/3600

but this works val = val * 0.00027778 (which is exactly the same)

Is there something I do wrong or are there some specifications of arduino I should know?

Thank you!

Martin
