| procedure: - z1 z2 | procedure: - z | procedure: - z1 z2 ... | procedure: / z1 z2 | procedure: / z | procedure: / z1 z2 ... | | With two or more arguments, these procedures return the difference | or quotient of their arguments, associating to the left. With one | argument, however, they return the additive or multiplicative | inverse of their argument. | | ... | | (/ 0.0) ==> +nan.0 | (/ 1.0 0) ==> +inf.0 | (/ -1 0.0) ==> -inf.0 | (/ +inf.0) ==> 0.0 If 0.0 is the multiplicative inverse of +inf.0, then +inf.0 must be multiplicative inverse of 0.0. But (/ 0.0) ==> +nan.0. Which line is correct?
