@runsun, ' isint(int(x))' I presume your int() function returns undef or
nan when x is not a number?
Not exactly. It will try to type-cast x into an int. So int("3.3")=> 3. The
test cases for int() are:
int ( x )=int ( tested:22 ) (mode:12)
| 0> int(3)= 3
| 1> int(3.3)= 3
| 2> int(-3.3)= -3
| 3> int(3.8)= 4
| 4> int(9.8)= 10
| 5> int(-3.8)= -4
| 6> int("-3.3")= -3
| 7> int("-3.8")= -3 // !!Note this!!
| 8> int("3")= 3
| 9> int("3.0")= 3
| 10> int("0.3")= 0
| 11> int("34")= 34
| 12> int("-34")= -34
| 13> int("-34.5")= -34
| 14> int("345")= 345
| 15> int("3456")= 3456
| 16> int("789987")= 789987
| 17> int("789.987")= 789 // !!Note this!!
| 18> int([3,4])= undef
| 19> int("x")= undef
| 20> int("34-5")= undef
| 21> int("34x56")= undef
I apologize that I didn't realize there are couple of user functions used. I
double checked and see that it'd take too much work trying to put all of
them here ('cos they also use other user functions). So maybe just remove
the "range detection" part ? I suppose not many ppl will need it, anyway.

Hi Runsun,
I had not thought of str(x)==x to test for a string, thanks.

Hi Doug,
You have my vote - type tests of the form is_int etc. would be nice to have
since they would be guaranteed to be robust.
