cpp/experimental/special functions/laguerre

@1@ Computes the non-associated Laguerre polynomials of the degree 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 nonassociated Laguerre polynomial of, that is $(xn )$, is returned.

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 is greater or equal than 128, the behavior is implementation-defined
