I checked in a fix for this. Likewise for gcd and lcm.

My preliminary response: This is a bug in R5RS and R7RS.
(numerator 5.5) should be a type error.

Kawa gives a type error if you try (numerator 5.5) or (denominator 5.5), instead of converting the inexact value to a ratio, getting the ratio numerator or denominator, and then making it inexact again. This is what R5RS and R7RS demand, because the argument can be any rational number, exact or inexact.

I've reported this bug for Chicken and Chibi, and I'm going to do so for RScheme and S7 too.
