Assert_LReal_Equal (FUN)¶

FUNCTION Assert_LReal_Equal : BOOL

Assertion function to check equality of two values of type LREAL.

The assertion succeeds for (referenceValue - precision) <= actualValue AND (referenceValue + precision) >= actualValue

InOut:

Scope	Name	Type	Initial	Comment
Return	`Assert_LReal_Equal`	`BOOL`		`TRUE` if the assertion passes succesfully, `FALSE` otherwise
Input	`context`	IBaseIecUnitTest		The instance of the test function block calling this function. This instance can be provided by using `THIS^`.
	`referenceValue`	`LREAL`		The expected value
	`actualValue`	`LREAL`		The value to check
	`precision`	`LREAL`	0.0	A value to specify an allowed deviation. Default is 0.0
	`wsErrorMsg`	`WSTRING(Constants.WSTRING_LENGTH)`	“”	A custom error message, that is added to the error message of the assertion itself. If this parameter is used, it is recommended to adapt the value of the library parameter Constants.WSTRING_LENGTH.
