 Methods

FALSE

FALSE() : boolean
Static

Returns the boolean FALSE.

Excel Function: =FALSE()

access public
category Logical Functions

Returns

booleanFalse

IFERROR

IFERROR(mixed $testValue, mixed $errorpart) : mixed
Static

Excel Function: =IFERROR(testValue,errorpart)

access public
category Logical Functions

Parameters

$testValue

mixed

Value to check, is also the value returned when no error

$errorpart

mixed

Value to return when testValue is an error condition

Returns

mixedThe value of errorpart or testValue determined by error condition

LOGICAL_AND

LOGICAL_AND() : boolean
Static

Returns boolean TRUE if all its arguments are TRUE; returns FALSE if one or more argument is FALSE.

Excel Function: =AND(logical1[,logical2[, ...]])

The arguments must evaluate to logical values such as TRUE or FALSE, or the arguments must be arrays
    or references that contain logical values.

Boolean arguments are treated as True or False as appropriate
Integer or floating point arguments are treated as True, except for 0 or 0.0 which are False
If any argument value is a string, or a Null, the function returns a #VALUE! error, unless the string holds
    the value TRUE or FALSE, in which case it is evaluated as the corresponding boolean value
access public
category Logical Functions

Returns

booleanThe logical AND of the arguments.

LOGICAL_OR

LOGICAL_OR() : boolean
Static

Returns boolean TRUE if any argument is TRUE; returns FALSE if all arguments are FALSE.

Excel Function: =OR(logical1[,logical2[, ...]])

The arguments must evaluate to logical values such as TRUE or FALSE, or the arguments must be arrays
    or references that contain logical values.

Boolean arguments are treated as True or False as appropriate
Integer or floating point arguments are treated as True, except for 0 or 0.0 which are False
If any argument value is a string, or a Null, the function returns a #VALUE! error, unless the string holds
    the value TRUE or FALSE, in which case it is evaluated as the corresponding boolean value

Returns

booleanThe logical OR of the arguments.

NOT

NOT(mixed $logical) : boolean
Static

Returns the boolean inverse of the argument.

Excel Function: =NOT(logical)

The argument must evaluate to a logical value such as TRUE or FALSE

Boolean arguments are treated as True or False as appropriate
Integer or floating point arguments are treated as True, except for 0 or 0.0 which are False
If any argument value is a string, or a Null, the function returns a #VALUE! error, unless the string holds
    the value TRUE or FALSE, in which case it is evaluated as the corresponding boolean value

Parameters

$logical

mixed

A value or expression that can be evaluated to TRUE or FALSE

Returns

booleanThe boolean inverse of the argument.

STATEMENT_IF

STATEMENT_IF(mixed $condition, mixed $returnIfTrue, mixed $returnIfFalse) : mixed
Static

Returns one value if a condition you specify evaluates to TRUE and another value if it evaluates to FALSE.

Excel Function: =IF(condition[,returnIfTrue[,returnIfFalse]])

Condition is any value or expression that can be evaluated to TRUE or FALSE.
    For example, A10=100 is a logical expression; if the value in cell A10 is equal to 100,
    the expression evaluates to TRUE. Otherwise, the expression evaluates to FALSE.
    This argument can use any comparison calculation operator.
ReturnIfTrue is the value that is returned if condition evaluates to TRUE.
    For example, if this argument is the text string "Within budget" and the condition argument evaluates to TRUE,
    then the IF function returns the text "Within budget"
    If condition is TRUE and ReturnIfTrue is blank, this argument returns 0 (zero). To display the word TRUE, use
    the logical value TRUE for this argument.
    ReturnIfTrue can be another formula.
ReturnIfFalse is the value that is returned if condition evaluates to FALSE.
    For example, if this argument is the text string "Over budget" and the condition argument evaluates to FALSE,
    then the IF function returns the text "Over budget".
    If condition is FALSE and ReturnIfFalse is omitted, then the logical value FALSE is returned.
    If condition is FALSE and ReturnIfFalse is blank, then the value 0 (zero) is returned.
    ReturnIfFalse can be another formula.
