Personally, I would take the approach that anything that distof is able to convert is a valid numerical input, since any input which may be converted using distof can also be generated using rtos.

Code: [Select]
(if (wcmatch str "*@*")
  (princ "\nIt is a string.")
  (princ "\nIt is a number")
)

Code: [Select]
(if (wcmatch str "*@*")
  (princ "\nIt is a string.")
  (princ "\nIt is a number")
)
Comando: (if (wcmatch "." "*@*")   (princ "\nIt is a string.")  (princ "\nIt is a number"))
=> It is a number
