!> 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
