statementIf()

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.

Parameters

Returns

The value of returnIfTrue or returnIfFalse determined by condition

statementSwitch()

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).
