RHS Value

Awaiting user input

Hello,

I get the RHS value of constraints with:

for c in model.getConstrs():

c.rhs

However, for the RHS values less than 0.05, c.rhs gives 0. I would like to know whether it is possible to obtain the exact value of RHS in any case.

Thank you for your help.

The RHS attribute should capture the exact value of the constraint's right-hand side. Note that Gurobi moves all constants in the constraint over to the right-hand side:
```
>>> c = m.addConstr(x + 0.03125 <= 0.0625)
>>> m.update()
>>> c.RHS
0.03125
```
Alternatively, is it possible the printed RHS values are formatted to show only one decimal place?

If neither of those suggestions help, can you please post a few lines of self-contained code that reproduce the behavior you're seeing? It would also be helpful to know where you are running the code (in an interactive shell, Jupyter notebook, IDE, etc.).
