Logarithmic and exponential equations

[orange]

Hi
How can we write logarithmic and exponential equations in setAttribute?
For logarithmic one, I have an equation like this: -316,2*log(x) + 622,73
For exponential one, I have an equation like this: 405*x^3 + 200*x^2

For logaritmic I've tried these but they don't work. For exponentials I don't know how? :)

FXUnit.setAttribute(FXUnit.Gain, -316.2*log(value) + 622.73);	 

FXUnit.setAttribute(FXUnit.Gain, -316.2*ln(value) + 622.73);

The Math object has all calculus methods:

Math.log, Math.pow, etc.
