LOGICAL_AND() : boolean
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 valueThe logical AND of the arguments.
LOGICAL_OR() : boolean
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 valueThe logical OR of the arguments.
NOT(mixed $logical = false) : boolean
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.
STATEMENT_IF(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
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
