Functional Slide Rule door BrianZ

This is an actual functioning slide rule to multiply, divide, find squares and roots. Ctrl-F to show sliding scale D, then move window bottom up until scale D meets scale C, then move window sides to slide scale D along scale C to multiply & divide. Read squares and roots directly from scales B and C. Works best at higher screen resolutions; toolbars set for no tabs on top and 100 pixels of header showing.
