DRAFT RESOLUTION:
6.13.6 COUNT
Summary: Count the number of Numbers provided.
Syntax: COUNT( { NumberSequenceList N }+ )
Returns: Number
Constraints: One or more parameters.
Semantics: Counts the numbers in the list N. Only numbers in references are counted; all other types are ignored. Errors are not propagated. This function does not propagate Error values. It is implementation-defined what happens if 0 parameters are passed, but it should be an Error or 0.
See also COUNTA 6.13.7
6.13.7 COUNTA
Summary: Count the number of non-empty values.
Syntax: COUNTA( { Any AnyValue }+ )
Returns: Number
Constraints: None.
Semantics: Counts the number of non-blank values. A value is non-blank if it contains any content of any type, including an Error. In a reference, every cell that is not empty is included in the count. An empty string value ("") is not considered blank. Errors contained in a range are considered a non-blank value for purposes of the count ; errors do not propagate . Constant expressions or formulas are allowed; these are evaluated and if they produce an Error value the Error value is counted as one non-blank value (and not propagated as an Error) . This function does not propagate Error values. It is implementation-defined what happens if 0 parameters are passed, but it should be an Error or 0.

6.13.11 ERROR.TYPE
Summary: Returns Number representing the specific Error type.
Syntax: ERROR.TYPE( Error E )
Returns: Number
Constraints: None.
Semantics: Returns a number representing what kind of Error has occurred. Note that unlike most functions, This function does not propagate Error values. Receiving a non-Error value returns an Error. In particular, ERROR.TYPE(NA()) returns 7, and ERROR.TYPE applied to a non-Error returns an Error.

6.13.12 FORMULA
Summary: Returns formula at given reference as text.
Syntax: FORMULA( Reference X )
Returns: String
Constraints: Reference X shall contain a formula.
Semantics: Returns the formula in reference X as a string. The specific syntax of this returned string is implementation-defined. This function is intended to aid debugging by simplifying display of formulas in other cells. Error results of the referred formula cell are not propagated. This function does not propagate Error values.

6.13.15 ISERR
Summary: Return TRUE if the parameter has type Error and is not #N/A, else return FALSE.
Syntax: ISERR( Scalar X )
Returns: Logical
Constraints: None
Semantics: If X is of type Error, and ISNA(X) is not true, returns TRUE. Otherwise it returns FALSE. Note that this function returns FALSE if given #N/A; if this is not desired, use ISERROR 6.13.16. Note that This function does not propagate Error values.
ISERR(X) is the same as:
IF(ISNA(X),FALSE(),ISERROR(X))

6.13.16 ISERROR
Summary: Return TRUE if the parameter has type Error, else return FALSE.
Syntax: ISERROR( Scalar X )
Returns: Logical
Constraints: None
Semantics: If X is of type Error, returns TRUE, else returns FALSE. Note that this function returns TRUE if given #N/A; if this is not desired, use ISERR 6.13.15. Note that This function does not propagate Error values.
