    Constants are off. Not the current values as they should be. Makes the constants almost useless. Still seems like the best advanced scientific calc app in the play store.

    For those engineers and scientists, this is the calculator app to have. However, it is a little difficult to edit previous entries. The edit mode may have a bug.
