hello everyone ....
 
I have MILP optimization problem. when I solve the problem and use the get_values function:
 
Although I sets the variables BINARY but it give me real values like(+0.0) or (-0.0)....
it caused I get the value wrong because when i check the value ==0 or ==1 in this case i receive  the wrong answer.....
 
any suggestion.....???
 
Thanks 
Aissan

There should not be any problem with that since:

    sage: -0.0 == 0
    True
    sage: 0.0 == 0 
    True

Could you provide a concrete example ?

yes I checked ........ I found the problem .... I used the get value, since it give me the real value sometimes it give some value near the zero or one

I considered the if which check the value if it bigger than 0.5 it consider 1 otherwise zero ...... anyway I am so grateful for all your consideration ...
