-/*
- * hexfloat.c provides routines that vfprintf and vfwprintf can call to convert
- * floating point numbers to hexidecimal, as used by the %a and %A conversions.
- * This is necessarily dependent not only on the floating point data format,
- * but also byte order and existence of long double type.
- *
- * The union hexdouble represents the IEEE-754 double precision format, while
- * union hexlongdouble represents the IEEE-754 extended double precision
- * format.
