Method Detail

calcAnd

protected static Ptg calcAnd(Ptg[] operands)

AND Returns TRUE if all its arguments are TRUE; returns FALSE if one or more arguments is FALSE. Syntax AND(logical1,logical2, ...) Logical1, logical2, ... are 1 to 30 conditions you want to test that can be either TRUE or FALSE. The arguments must evaluate to logical values such as TRUE or FALSE, or the arguments must be arrays or references that contain logical values. If an array or reference argument contains text or empty cells, those values are ignored. If the specified range contains no logical values, AND returns the #VALUE! error value.

calcIf

protected static Ptg calcIf(Ptg[] operands)

IF Returns one value if a condition you specify evaluates to TRUE and another value if it evaluates to FALSE. Use IF to conduct conditional tests on values and formulas. Syntax 1 IF(logical_test,value_if_true,value_if_false) Logical_test is any value or expression that can be evaluated to TRUE or FALSE. Value_if_true is the value that is returned if logical_test is TRUE. If logical_test is TRUE and value_if_true is omitted, TRUE is returned. Value_if_true can be another formula. Value_if_false is the value that is returned if logical_test is FALSE. If logical_test is FALSE and value_if_false is omitted, FALSE is returned. Value_if_false can be another formula. Remarks Up to seven IF functions can be nested as value_if_true and value_if_false arguments to construct more elaborate tests. See the following last example. When the value_if_true and value_if_false arguments are evaluated, IF returns the value returned by those statements. If any of the arguments to IF are arrays, every element of the array is evaluated when the IF statement is carried out. If some of the value_if_true and value_if_false arguments are action-taking functions, all of the actions are taken.

calcFalse

protected static Ptg calcFalse(Ptg[] operands)

Returns the logical function False

calcTrue

protected static Ptg calcTrue(Ptg[] operands)

Returns the logical function true

calcNot

protected static Ptg calcNot(Ptg[] operands)

Returns the opposite boolean

calcOr

protected static Ptg calcOr(Ptg[] operands)

Returns the opposite boolean

calcIferror

protected static Ptg calcIferror(Ptg[] operands)

IFERROR function Returns a value you specify if a formula evaluates to an error; otherwise, returns the result of the formula. Use the IFERROR function to trap and handle errors in a formula (formula: A sequence of values, cell references, names, functions, or operators in a cell that together produce a new value. A formula always begins with an equal sign (=).). Value is the argument that is checked for an error. Value_if_error is the value to return if the formula evaluates to an error. The following error types are evaluated: #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL!. Remarks If value or value_if_error is an empty cell, IFERROR treats it as an empty string value (""). If value is an array formula, IFERROR returns an array of results for each cell in the range specified in value. See the second example below.
