The reciprocal of any real or complex number is equal to 1 [[divide]]d by that number. Therefore the monadic <source lang=apl inline>÷</source> can be seen as dyadic <source lang=apl inline>÷</source> with default left argument of 1. This applies even to the reciprocal of 0; <source lang=apl inline>÷0</source> and <source lang=apl inline>1÷0</source> show identical behavior for both <source lang=apl inline>⎕DIV←0</source> (raising [[DOMAIN ERROR]]) and <source lang=apl inline>⎕DIV←1</source> (returning 0). | |||
