[thelist] js validating numbers

[Erik Mattheis]

oops reread message ... sorry ....  try:

function returnTypeOfNum(chk) {
   if (parseInt(chk) == chk) {
     return 'integer';
   else if (!isNaN(chk)) {
     return 'decimal number';
   }
   else {
     return 'no sort of number';
   }
}

but still not sure what you mean by:

What would the question be that could be answered by a number or
percentage that would be meaningful without the user indicating so?
