 Tests with pairs of numbers (x,y):


 Inf inputs where x < y:


    (1) (-Inf,   0)


    (2) ( 0  , Inf)


    (3) (-Inf, Inf)


 Inf inputs where x > y:


    (4) ( 0  ,-Inf)


    (5) ( Inf,   0)


    (6) ( Inf,-Inf)


 NaN inputs to test NaN propagation:


    (7) ( 0  , NaN)


    (8) ( NaN,   0)


 The program tests MIN(x,y) and MAX(x,y) for every pair
