-********************************************************************************
-*     The C math library offers a similar function called "frexp".  It is      *
-*     different in details from logb, but similar in spirit.  This current     *
-*     implementation of logb follows the recommendation in IEEE Standard 854   *
-*     which is different in its handling of denormalized numbers from the IEEE *
-*     Standard 754.                                                            *
