description

    
Implementations should be permitted to distinguish 0.0 from -0.0 in accordance with IEEE 754.  `0.0` and `-0.0` should be the same to `=` and friends, but should be distinguishable by `eqv?`.

Mathematically, negative inexact zero represents a number greater than the largest representable negative inexact number and less than or equal to 0.  This is different from positive inexact zero, which represents a number greater than or equal to 0 and less than the smallest representable positive inexact number.
