# Accessing Table Function Values

To get the value of a table function for some argument, call
the table function as any other function by its name, passing
the argument value as the function parameter. For instance, if you have
a table function named lookup1 in your model, to get the function value for the argument 5, call:

lookup1(5);

Alternatively, you can use the function get(double x) of the table function. For the example, considered above, the function call should be:

lookup1.get(5);

Both functions are identical. They return the table function
value corresponding to the given argument, subject to the currently set
interpolation type and out of range handling. In case the function only
supports discrete values (that were provided
as the argument set), and no interpolation is allowed, a call of such a
function with an argument not matching any argument entry would
result in exception thrown.
