//   __eqsf2   __gesf2   __unordsf2

// The semantics of the routines grouped in each column are identical, so there

// The main routines behave as follows:
//
//   __lesf2(a,b) returns -1 if a < b
//                         0 if a == b
//                         1 if a > b
//                         1 if either a or b is NaN
//
//   __gesf2(a,b) returns -1 if a < b
//                         0 if a == b
//                         1 if a > b
//                        -1 if either a or b is NaN
//
//   __unordsf2(a,b) returns 0 if both a and b are numbers
//                           1 if either a or b is NaN
//
// Note that __lesf2( ) and __gesf2( ) are identical except in their handling of
