If If BooleanExpr1 Then Block1 ElseIf BooleanExpr2 Then Block2 © ElseIf BooleanExprN Then BlockN EndIf Allows for branching. If BooleanExpr1 evaluates to true, executes Block1. If BooleanExpr1 evaluates to false, evaluates BooleanExpr2, and so on. Catalog > ifFn( ) Catalog > ifFn(BooleanExpr,Value_If_true [,Value_If_false [,Value_If_unknown]]) ⇒ expression, list, or matrix Evaluates the boolean expression BooleanExpr (or each element from BooleanExpr ) and produces a result based on the following rules: • BooleanExpr can test a single value, a list, or a matrix. • If an element of BooleanExpr evaluates to true, returns the corresponding element from Value_If_true. • If an element of BooleanExpr evaluates to false, returns the corresponding element from Value_If_false. If you omit Value_If_false, returns undef. • If an element of BooleanExpr is neither true nor false, returns the corresponding element Value_If_unknown. If you omit Value_If_unknown, returns undef. • If the second, third, or fourth argument of the ifFn() function is a single expression, the Boolean test is applied to every position in BooleanExpr. Test value of 1 is less than 2.5, so its corresponding Value_If_True element of 5 is copied to the result list. Test value of 2 is less than 2.5, so its corresponding Value_If_True element of 6 is copied to the result list. Test value of 3 is not less than 2.5, so its corresponding Value_If_False element of 10 is copied to the result list. Value_If_true is a single value and corresponds to any selected position. Note: If the simplified BooleanExpr statement involves a list or matrix, all other list or matrix arguments must have the same dimension(s), and the result will have the same dimension(s). Value_If_false is not specified. Undef is used. imag( ) imag(Value1) ⇒ value Returns the imaginary part of the argument. imag(List1) ⇒ list Returns a list of the imaginary parts of the elements. One element selected from Value_If_true. One element selected from Value_If_unknown. Catalog > 46 TI-Nspire™ Reference Guide
