Thanks for pointing this out.  The SRFI is of course wrong:  the paradigm
case of +nan.0 is (/ 0.0 0.0), and the value of this is not any of the
real numbers.

Arise, you prisoners of Windows / Arise, you slaves of Redmond, Wash,
The day and hour soon are coming / When all the IT folks say "Gosh!"
It isn't from a clever lawsuit / That Windowsland will finally fall,
But thousands writing open source code / Like mice who nibble through a wall.
