Which source tells you 8.3 X 11.7 in is the exact and only A4 size?
First of all, 8.3 X 11.7 in is the 8.26 X 11.69 in rounded to one decimal
digit, and even 8.26 X 11.69 in is not exact, merely rounded.
Please be aware that the An formats are defined by some criterion and then
rounded to the nearest millimeter. Thus, the size in inches usually has
numerous decimal digits. Assuming a single decimal number to be exact,
therefore, is presumptuous.
Furthermore, the standard also defines tolerances. If the size differs by
nor more than that tolerance from the 'exact' value, the format still is An.

This shows that the person who implemented the validation code not only has
not understood ISO 216 (which defines most of the An sizes) but also has not
understood floating point numbers. Almost always doing '==' on floats is
nonsense.
