"0.32 with a line above it" could refer to two possible numbers, either [tex]0.\overline{32}=0.323232\ldots[/tex] or [tex]0.3\overline2=0.3222\ldots[/tex].
In either case, 0.32 will be the smaller of the two numbers simply because it terminates with two digits after the decimal point, while the others keep going, basically adding a small positive number to 0.32.
