No, you are checking whether it can be interpreted as a valid integer or
fixed-point decimal value.  One cannot tell what a string IS by mere
inspection of the string.

Doing your own work where reasonable is good.  But regurgitating all the
old and well-known follies here is not good.  We on the whole, or I at
least, would prefer you to take advantage of what is already well-known
and sufficiently published in the field, and then to present new and
therefore interesting problems, so encouraging the advancement of
learning in general.

Remember what Newton said about the shoulders of giants.  And note that
he probably did not invent that saying, but more likely got it
indirectly from Bernard of Chartres.
