Observe that

(window-total-width 'round)

should get you

(wrong-type-argument window-valid-p round)

As a rule `window-' prefixed functions require a window as first
argument.

The form to evaluate should be either (window-total-width nil 'ceiling)
or (window-total-width nil 'floor).  Any other value for ROUND behaves
like `window-total-width' called without ROUND argument.
