 Class Precedence List:
floating-point-invalid-operation,
arithmetic-error,
error,
serious-condition,
condition,
t
Description:
The type floating-point-invalid-operation consists of
error conditions that occur because of certain 
floating point traps. 
It is implementation-dependent whether floating point traps
occur, and whether or how they may be enabled or disabled.  Therefore,
conforming code may establish handlers for this condition, but must not
depend on its being signaled.
