CX-programer Math function

[marcinmrag]

Hello everyone!

I have a question. I have a function : y=1E-06x6 - 0,0001x5 + 0,0043x4 - 0,0797x3 + 0,6374x2 - 1,5325x - 0,3771 . It's a  characteristic that i would like to compare. It's the way that i can easy create some function block that will calculate this? I know that in siemens is something like a math function and than we can put this function and do calculation. I tried to do this in ST in function blok but i have a problem with x6 

Any Ideas?
