No, it's more complicated than that. Actually, it's not that complicated
if you explain it the other way around:
- The only case in which a char-by-char comparison is made, is if both
arguments are strings, and at least one of them doesn't "look" like a number.
Or, in other words:
- If at least one of the arguments is not a string, a numeric comparison is
made.
- If both arguments are strings, but both of them look like numbers, a
numeric comparison is made.
- If both arguments are strings (and at least one of them doesn't look like
a number), a string comparison is made.
