18.104.22.168.2 Printing Ratios
Ratios are printed as follows:
the absolute value of the numerator is printed, as for an integer;
then a /; then the denominator. The numerator and denominator are
both printed in the radix specified by the current output base;
they are obtained as if by
numerator and denominator, and so ratios
are printed in reduced form (lowest terms).
If appropriate, a radix specifier can be printed; see
If the ratio is negative, a minus sign is printed before the numerator.
