F_BACnet_RealEQ : BOOL
Application
Function for comparing two floating-point values taking into account the value range. This function should be used instead of the standard operators ("=" or "EQ") for values from BACnet, since otherwise a PLC stop is triggered if the values to be compared are not in the finite range (e.g. not-a-number values).
VAR_INPUT
fIn1 : REAL;
fIn2 : REAL;
Return value: TRUE = fIn1 and fIn2 are identical or both are not in the finite value range. FALSE = fIn1 and fIn2 are different.
