Polynomial coefficient 0 to 4

On sensor = resistor log. polynomial: calculation of temperature by logarithmic polynomial.
Input of the coefficients of shape

• y(x) = 1 / ( n₄⋅(ln(x)) ⁴ + n₃⋅(ln(x)) ³ + n₂⋅(ln(x)) ² + n₁⋅ln(x) + n₀) – y₀

If n₂ = n₄ = 0 the formula corresponds of the temperature calculation according to the Steinhart-Hart-Equation.
