Added static cast from double to float

[sisco0]

Closes #3677
Compile warnings have been fixed, double and float types where having issues when double values were assigned to a float type vector. In this case, the solution was just using a static_cast<float>(doubleVal) construction, which would lower the double value precission in order to fill the target float space.

There is to say that there could be a data loss during this process (not anything different than before), so it should be studied if double is the desired type for the features_values vector or it should be float type.

It would be desirable to use .at() instead of [] in order to throw exceptions when incorrect array positions are consulted.
