Return value

Possible numerators include the gross income net pretax income net after-tax income gross profit, ie, gross income minus book depreciation cash flow or net income. An average return value is selected by defining a typical or mature proof year as the basis of calculation. The denominator can be the original total investment, depreciated book-value investment, lifetime averaged investment, or fixed capital investment. 

Using MATLAB to design a system, it is possible to superimpose lines of constant ( and ajn on the root locus diagram. It is also possible, using a cursor in the graphics window, to select a point on the locus, and return values for open-loop gain K and closed-loop poles using the command...

The task of the problem-independent chemistry software is to make evaluating the terms in Equations (6-10) as straightforward as possible. In this case subroutine calls to the Chemkin software are made to return values of p, Cp, and the and hk vectors. Also, subroutine calls are made to a Transport package to return the ordinary multicomponent diffusion matrices Dkj, the mixture viscosities p, the thermal conductivities A, and the thermal diffusion coefficients D. Once this is done, finite difference representations of the equations are evaluated, and the residuals returned to the boundary value solver. 

Specifically, parameterized attributes are constrained by static invariants. In contrast, any operation is defined by its pre- and postcondition (see Section 3.1.2, Pie- and Postconditions Specify Actions) a read-only operation would have a postcondition that defined the returned value in terms of the inputs and current state. 

An action can have a return type whose return value is the identity of a new or preexisting object used by the sender. Within the postcondition, result is the conventional name given to this value. Any actions can have a return value those that have no other side effects are called functions. 

Input parameters represent object references that are provided by the caller return values represent object references returned to the caller to deal with as needed. Although out parameters can be broadly considered similar to return values, the details are somewhat different. The postcondition of the operation will determine the value of the out parameter and its attributes however, the client will call this operation with these out parameters bound to an attribute selected by the client. 

In the specification of a localized action, self is defined and refers to the receiving object. We do not know who the invoker is. Return values (e.g., price) can be defined. 

The choice of types for a local variable—temporaries, inputs, and even return values— for an operation is crucial to good decoupling. As soon as you declare a variable or parameter that belongs to a particular class, you have made your part of the program dependent on that class. This means that any changes there may have an impact here. Instead, it is usually better to declare all variables as types, the only place in a program where you absolutely must refer to a concrete class is to instantiate a new object. 

Different languages have different mechanisms to indicate exceptions return values, exception objects thrown, signals raised, and so on. For specification purposes, you can work with any of these, including some language-neutral mechanisms (such as return val-... 

Connectors that support explict call and return The call could be synchronous or asynchronous. Asynchronous messages could be queued until processed, and return values could be treated as futures5 or callbacks. 

An output event can transfer information in two directions via parameters and via the return value normally associated with function calls. For that reason, an output event can have a postcondition at the sending end.13... 

Future, a promise of a return value that can be returned eagerly and passed around. When its value is finally accessed, it may block the accessor if the value is not yet available. 

As we discussed, for a matrix of the form XTX this implies singularity. For a general symmetric matrix, however, the return value ER = 1 does not necessarily imply its singularity, and you can still try to use the modules M14 and M15 in order to invert the matrix. 

The only potential trouble is A = , which gives the return value of the status flag ER = 1. The return value of MR is the number of real roots. If NR = 3, the real roots will occupy the variables XI, X2 and X3. If MR = 1 then the only real root will occupy X, whereas you will find the real and imaginary parts of the conjugate complex pair in the variables XR and XI, respectively. 

Since the covariance matrix is diagonal, a vector denoted by V is used to store the variances. If the number of balances does not exceed ten, the module also computes the tabular value of the chi square distribution at significance level a = 0.05 and degrees of freedom nb. The return value ER = 1 of the status flag indicates that the rows of the matrix W are linearly dependent, and hence you should drop at least one of the balance equations. If the source of linear dependence is not clear then the module M10 can help to uncover it. 

The return value ER = 2 of the status flag indicates that the functional relationships (3.B5) are linearly dependent, i.e., at least one of the equations can be omitted.

Rwork(4) contains the endpoint of the latest completed integration step. The returned value of t may differ when Idid=3, 4, or 5 because of interpolations then performed. 

Most worksheet functions require one or more arguments the values that the function uses to calculate a return value. The arguments are enclosed in parentheses following the function name, e.g., SQRT(125) or SUM( F 3 F 28) or SUBSTITUTE(PartNumber, "-1995, "-1996"). A few functions, such as Pl() or NOW(), do not require arguments, but the opening and closing parentheses must still be provided. 

IF(NOT(ISERROR(logical expression)),valueJf true,value if false) returns value if true if logicaLexpression does not return an error value. 

Excel Tip. Use the vector form of LOOKUP (instead of e.g., VLOOKUP) when you need to return a value from a column to the left of the column containing the lookup values, or when your lookup values are in a column and your return values are in a row. 

The data table (Figure 11-7) has been compressed by hiding rows containing some of the less interesting data. To obtain the regression parameters, a 3R x 4C array was selected on the spreadsheet and the formula =LINEST(G5 G37,B5 E37,0,1) was entered. Since an array is to be returned, the array formula was entered by using COMMAND+ENTER (Macintosh) or CONTROL+SHIFT+ENTER (Windows). The array of returned values is shown in Figure 11-8. 

The major limitation of the regression tool is that, unlike FINEST, it is not a function. With FINEST, the returned values are dynamically linked to the original data and are updated if the raw data is changed. With the Regression tool, the values are calculated from the raw data and entered into worksheet cells they do not change if you change the input data. 

As well as performing an action, methods create a return value. The return value can be either True or False. Even the ChartWizard method creates a return value True if the chart was created successfully, False if the method failed. Usually you aren t interested in these return values. 

An example of a method that creates a useful return value is the Checkspelling method. The CheckSpelling method has the following s)mtax ... 

If you use this method, you ll need the return value (either True or False) to determine whether the word is spelled correctly. 

If you want to use the return value of a method, you must enclose the arguments of the method in parentheses. If the arguments are not enclosed in parentheses, then the return value will not be available for use. Put another way, the expression... 

You can also specify the data type of the return value. If none is specified, the Variant data type will be returned. In the example of the preceding section, MolWt returns a floating-point result. The Variant data type is satisfactory ... 

MsgBox returns a value that indicates which button was pressed. This allows you to take different actions depending on whether the user pressed the Yes, No or Cancel buttons, for example. To get the return value of the Message Box, use an expression like... 

The differences between the InputBox function and the InputBox method are the following (i) default can be any data type and (ii) the additional argument type num specifies the data type of the return value. The values of type num and the corresponding data types are listed in Table 14-7. Values of type num can be added together. For example, to specify an input dialog box that would accept number or string values as input, use tiie value 1 + 2 = 3 for type num.
