Apparently math is not one of Dougy's strengths. He is so intent on jumping
down people's throats he doesn't think before he types, anymore.

Tangent tables and formulae in calculators are seldom more accuracy than 5
places of accuracy, even though displaying 10 places. The errors can seem
way out-to-lunch at times with multiple steps.

Where did you get "3 significant digits" from? 0.75 has only two.
