| 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
