true()
true() : boolean
TRUE.
Returns the boolean TRUE.
Excel Function: =TRUE()
Returns
boolean —True
logicalAnd(mixed ...$args) : boolean|string
LOGICAL_AND.
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| mixed | $args variadic | Data values |
the logical AND of the arguments
logicalOr(mixed $args) : boolean|string
LOGICAL_OR.
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| mixed | $args | Data values |
the logical OR of the arguments
logicalXor(mixed $args) : boolean|string
LOGICAL_XOR.
Returns the Exclusive Or logical operation for one or more supplied conditions. i.e. the Xor function returns TRUE if an odd number of the supplied conditions evaluate to TRUE, and FALSE otherwise.
Excel Function: =XOR(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| mixed | $args | Data values |
the logical XOR of the arguments
NOT(mixed $logical = false) : boolean|string
NOT.
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| mixed | $logical | A value or expression that can be evaluated to TRUE or FALSE |
the boolean inverse of the argument
statementIf(mixed $condition = true, mixed $returnIfTrue, mixed $returnIfFalse = false) : mixed
STATEMENT_IF.
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.| mixed | $condition | Condition to evaluate |
| mixed | $returnIfTrue | Value to return when condition is true |
| mixed | $returnIfFalse | Optional value to return when condition is false |
The value of returnIfTrue or returnIfFalse determined by condition
statementSwitch(mixed $arguments) : mixed
STATEMENT_SWITCH.
Returns corresponding with first match (any data type such as a string, numeric, date, etc).
Excel Function: =SWITCH (expression, value1, result1, value2, result2, ... value_n, result_n [, default])
Expression
The expression to compare to a list of values.
value1, value2, ... value_n
A list of values that are compared to expression. The SWITCH function is looking for the first value that matches the expression.
result1, result2, ... result_n
A list of results. The SWITCH function returns the corresponding result when a value matches expression.
default
Optional. It is the default to return if expression does not match any of the values (value1, value2, ... value_n).| mixed | $arguments | Statement arguments |
The value of matched expression
IFERROR(mixed $testValue = '', mixed $errorpart = '') : mixed
IFERROR.
Excel Function: =IFERROR(testValue,errorpart)
| mixed | $testValue | Value to check, is also the value returned when no error |
| mixed | $errorpart | Value to return when testValue is an error condition |
The value of errorpart or testValue determined by error condition
IFNA(mixed $testValue = '', mixed $napart = '') : mixed
IFNA.
Excel Function: =IFNA(testValue,napart)
| mixed | $testValue | Value to check, is also the value returned when not an NA |
| mixed | $napart | Value to return when testValue is an NA condition |
The value of errorpart or testValue determined by error condition
