Bug in verbose information when working with mixed-integer constraint problem

[udicaprio]

Hi,

I am working with mixed-integer constrained problem with verbose active. When display information about the iteration, the integer parameters appear with the prefix np.float making impossible to read what is the sample point (see image below for further information.

Apologies @udicaprio, I somehow missed this.

The conversion to print happens here. I guess, for some reason, calling str on the number doesn't output the actual value (though why it does for the float numbers, I don't know -- the printing should work the same way).

Do you have some short example that reproduces the problem? In e.g. the notebook it doesn't happen.

Hello @till-m, this happens only when the problem is discrete and constrained. The examples in the notebook do not take into account this scenario.

Should be fixed, let me know if it still happens.
