Operands
=========


Keyword VALEUR
--------------


.. code-block:: text

    ♦ VALEUR =

Keyword factor to test a value of a function or a table.


Operand FONCTION
~~~~~~~~~~~~~~~~~~


.. code-block:: text

    ♦ FONCTION = f

Name of the function (with one parameter) or of the table (with two parameters) on which the operation is performed.


Operand NOM_PARA
~~~~~~~~~~~~~~~~~~


.. code-block:: text

    ◊ NOM_PARA = the name

In the case of a function, this keyword is not processed.

In the case of a cable, the user will give 2 parameter names: the first defining the parameter of the cable, the second defining the parameter of the function you want to test (see the command DEFI_NAPPE [:ref:`U4.31.03 <U4.31.03>`]).


Operand VALE_PARA
~~~~~~~~~~~~~~~~~~


.. code-block:: text

    ♦ VALE_PARA = for

In the case of a function, the user gives the value of the parameter for which the value of the function is tested.

In the case of a tablecloth, the user gives the 2 values corresponding to the names of the two parameters (that of the tablecloth and that of the function).


Keywords common to orders TEST_XXX
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The definition of the non-regression and reference values, as well as the allowable tolerances, and the comparison criteria are detailed in the documentation [:ref:`u4.92.01 <u4.92.01>`] for the TEST_RESU command.

The specificities of TEST_FONCTION are:


* no integer values or character strings,


* no tolerance on the value of the parameter (TOLE_MACHINE and CRITERE take only one value).


Keyword ATTRIBUT
----------------


.. code-block:: text

    /ATTRIBUT =

Factor keyword to test an attribute of a function or a table.


Operand FONCTION
~~~~~~~~~~~~~~~~~~


.. code-block:: text

    ♦ FONCTION = f

Name of the function or the table on which the operation is performed.


Operand PARA
~~~~~~~~~~~~~


.. code-block:: text

    ◊ PARA = real

In the case of a function, this keyword is not necessary.

In the case of a tablecloth, the user gives the value of the parameter to retrieve the function in order to test the attribute.


Operands PREC_PARA/CRIT_PARA
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


.. code-block:: text

    ◊ PREC_PARA = prec

We are looking for the function defined by the value of the parameter in an interval defined by the absolute or relative position:

"inst±prec" (confer CRITERE [§3.2.3]).

By default prec = 1.0D-3.


.. code-block:: text

    ◊ CRIT_PARA =

'RELATIF': the search interval is: [:ref:`inst(1-prec),inst(1+prec) <inst(1-prec),inst(1+prec)>`]

'ABSOLU': the search interval is: [inst-prec, inst+prec]


Operand ATTR
~~~~~~~~~~~~~


.. code-block:: text

    ♦ ATTR =

The name of the attribute to be tested. For the meaning of attributes refer to DEFI_FONCTION [:ref:`U4.31.02 <U4.31.02>`] or DEFI_NAPPE [:ref:`U4.31.03 <U4.31.03>`].


Operand ATTR_REFE
~~~~~~~~~~~~~~~~~~~


.. code-block:: text

    ♦ ATTR_REFE = attr

Reference attribute. For the meaning of attributes refer to DEFI_FONCTION [:ref:`U4.31.02 <U4.31.02>`] or DEFI_NAPPE [:ref:`U4.31.03 <U4.31.03>`].
