Hi,

I am using python.

I have a problem with the value of a variable. I fix the lower and upper bound to "1" and then solve the problem and I get that the variable that is fixed takes a different value nearest to one.

print(y[15].ub)
print(y[15].lb)
print(y[15].x)

what it's showed:

1.0
1.0
0.9999999999999999

as you can see the value of the variable y[15] is 0.999999999 and I don´t know why is it happening?

Can you help me please to solve that problem.

  Hi Mishelle,

  Please see this article in our Knowledge Base: Why does Gurobi sometimes return non-integral values for integer variables?

  Best,
