Poly1

First order polynomial function. This function lets you calculate a simple first order polynomial transformation of the input value. The “a” parameter is the constant term, and the “b” parameter is the coefficient of the first order term. The Poly1 function is useful e.g., to convert from one unit to another.

Default parameter values:
	a = 0, b = 1

Example:
	a = 3, b = 2

	Input = 4.2  =>  Output = 	11.4
	Input = 8.5  =>  Output = 	20.0
