VALUENOTSUP

Message        <Context> the floating-point constant named "<name>"
               is not supported in "<fpmode>" representation.

Description    The representation of an IEEE Infinity or NaN has no
               special meaning when used with non-IEEE
               floating-point operations.

User Action    Replace the named constant with a conventional
               floating point constant.  The HUGE_VAL macros defined
               by <math.h> may be used in place of IEEE Infinities
               with any floating-point representation.
