A man ordered a size 14.50 special monster-design slipper to fit his oversized left foot. Instead, he was sent one at size 1,450 – because manufacturers failed to spot a decimal point.

Engineers used to rely on imprecise calculations with slide rules that only showed three decimal points and designed the Empire State Building, Saturn V rocket with them. As a result, they designed conservatively by making walls thicker and bridges stronger than needed
