...
Fast lookup transition on active data using the input value as entry for calculating an index in the resolution curve result buffer for direct lookup result. No extrapolation argument is allowed. The accuracy of the result depends on the size of the result buffer. The values in the result buffer is calculated through interpolation when they were created, but no further interpolation takes place when a value is returned..
