20.3.31 Details about the 2-point curve function
20.3.31.1 Behaviour
The module calculates the function value of the vale on
Input 0
using a 2-point curve progressi-
on and outputs the result ( f(
Input 0
) = y =
Output 0
)on the
Output 0
. The curve progression is
determined as linear slope between two points as follows (see also the graphic below):

The first point results from the values of the
Input 1
(x-coordinate) and of the
Input 2
(y-coordinate).

Analogue to this, the second point is defined by the values of the
Input 3
(x-
coordinate) and of the
Input 4
(y-coordinate).
If the point coordinates are invalidly configured (e.g. x-values identical) the result 1 (logical
"true") is output on
Output 1
.
The internal data type of the module is Number. If necessary, incoming values are converted
into the internal data type before the calculation (see conversion table below).
20.3.31.2 Extended settings
This module has no additional setting options.
