Task

This calculates the function value of an X standardized Poly5.

Description

This calculates the function value of an X standardized Poly5 at a given X-value i_lrX. The Poly5 is given by a structure of type ST_Poly5NormalizedCoefficients.

Interface

Input	Data type	Description
i_lrX	LREAL	X value for which the function value of the X standardized Poly5 is to be calculated
i_stNormalizedCoefficients	ST_Poly5NormalizedCoefficients	Coefficient structure which defines the polynomial to be evaluated

Output	Data type	Description
q_etDiag	GD.ET_Diag	General library-independent statement on the diagnostic. A value not equal to ET_Diag.Ok corresponds to an diagnostic message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnostic. q_etDiag = ET_Diag.Ok -> Status message q_etDiag <> ET_Diag.Ok -> Diagnostic message
