Enum Constant Summary

Enum Constants

Enum Constant and Description
DIV0 Intended to indicate when any number, including zero, is divided by zero.
NA Intended to indicate when a designated value is not available.
NAME Intended to indicate when what looks like a name is used, but no such name has been defined.
NULL Intended to indicate when two areas are required to intersect, but do not.
NUM Intended to indicate when an argument to a function has a compatible type, but has a value that is outside the domain over which that function is defined.
REF Intended to indicate when a cell reference is invalid.
VALUE Intended to indicate when an incompatible type argument is passed to a function, or an incompatible type operand is used with an operator.

Enum Constant Detail

NULL

public static final FormulaError NULL

Intended to indicate when two areas are required to intersect, but do not.

Example: In the case of SUM(B1 C1), the space between B1 and C1 is treated as the binary intersection operator, when a comma was intended. end example]

DIV0

public static final FormulaError DIV0

Intended to indicate when any number, including zero, is divided by zero. Note: However, any error code divided by zero results in that error code.

VALUE

public static final FormulaError VALUE

Intended to indicate when an incompatible type argument is passed to a function, or an incompatible type operand is used with an operator.

Example: In the case of a function argument, text was expected, but a number was provided

REF

public static final FormulaError REF

Intended to indicate when a cell reference is invalid.

Example: If a formula contains a reference to a cell, and then the row or column containing that cell is deleted, a #REF! error results. If a worksheet does not support 20,001 columns, OFFSET(A1,0,20000) will result in a #REF! error.

NAME

public static final FormulaError NAME

Intended to indicate when what looks like a name is used, but no such name has been defined.

Example: XYZ/3, where XYZ is not a defined name. Total is & A10, where neither Total nor is is a defined name. Presumably, "Total is " & A10 was intended. SUM(A1C10), where the range A1:C10 was intended.

NUM

public static final FormulaError NUM

Intended to indicate when an argument to a function has a compatible type, but has a value that is outside the domain over which that function is defined. (This is known as a domain error.)

Example: Certain calls to ASIN, ATANH, FACT, and SQRT might result in domain errors.

Intended to indicate that the result of a function cannot be represented in a value of the specified type, typically due to extreme magnitude. (This is known as a range error.)

Example: FACT(1000) might result in a range error.

NA

public static final FormulaError NA

Intended to indicate when a designated value is not available.

Example: Some functions, such as SUMX2MY2, perform a series of operations on corresponding elements in two arrays. If those arrays do not have the same number of elements, then for some elements in the longer array, there are no corresponding elements in the shorter one; that is, one or more values in the shorter array are not available.

This error value can be produced by calling the function NA

Method Detail

values

public static FormulaError[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FormulaError c : FormulaError.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FormulaError valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getCode

public byte getCode()

Returns:

numeric code of the error

getString

public java.lang.String getString()

Returns:

string representation of the error

forInt

public static FormulaError forInt(byte type)

forString

public static FormulaError forString(java.lang.String code)
