  /* Rounds the ratio {x/eps} to an integer. If {r} is negative, rounds
    to the nearest integer. If {r} non-negative, rounds to the nearest
    integer that congruent to {r} modulo {2}.
    
    In case of ties, rounds {x/eps} to the nearest even number if {r < 0}, 
    and to the nearest integer of the form {4*k + r} if {r} is 0 or 1. */
