Worth it if your function is acutely fundamental to the operation of your software because your software runs everyone else's software. You buy some time on a compute cluster with 1024 cores and 4TB of ram, and off you go, after making sure you understand your own code and reduce that number back down to "no it isn't, because two arguments in a given space for fundamental maths operations, taken together, almost certainly don't require combinatorial testing" =)
