@1@ Computes the of the degree, order , and argument @4@ A set of overloads or a function template accepting an argument of any integral type. Equivalent to after casting the argument to.

Return value
If no errors occur, value of the associated Laguerre polynomial of, that is $(-1)m L n+m(x)$, is returned (where $L n+m(x)$ is the unassociated Laguerre polynomial, ).

Error handling
Errors may be reported as specified in math_errhandling.


 * If the argument is NaN, NaN is returned and domain error is not reported
 * If is negative, a domain error may occur
 * If or  is greater or equal to 128, the behavior is implementation-defined.
