22.1.3.1.2 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 *print-radix*. If the ratio is negative, a minus sign is printed before the numerator.

For related information about the syntax of a ratio, see Section 2.3.2.1.2 Syntax of a Ratio.
