public class UltraCalcFunctionIf : BuiltInFunctionBase
IF( boolean_test, result_if_true, [result_if_false])
Boolean_test is a value (or an UltraCalc expression) which the IF function evaluates to produce a boolean value of either TRUE or FALSE. The outcome of this test determines which result will be returned by the function.
Result_if_true is a value (or the outcome of another UltraCalc expression) that will be returned only when boolean_test has evaluated to the boolean value, TRUE.
Result_if_false is a value (or the outcome of another UltraCalc expression) that will be returned only when boolean_test has evaluated to the boolean value, FALSE.
The IF function allows you to write an UltraCalc expression that branches to one expression (when the boolean_test is TRUE) or another (when the boolean_test is FALSE) based on an arbitrary condition you have specified.
The result_if_false is not specified and boolean_test is FALSE, the IF function will return FALSE.
If boolean_test's evaluation produces an error value then neither Result_if_true nor Result_if_false will be evaluated. Instead, the IF function returns the error value from its evaluation of boolean_test.
