Root: Difference between revisions

{{Built-in|Root|√}} (<source lang=j inline>%:</syntaxhighlight> in [[J]]) is a [[dyadic]] [[scalar function]] that computes the [[wikipedia:nth root|nth root]]; <source lang=apl inline>X√Y</syntaxhighlight> is equal to <source lang=apl inline>Y*÷X</syntaxhighlight>, the right [[argument]] raised to the [[power]] of the [[reciprocal]] of the left argument. The positioning of arguments resembles the [[Comparison with traditional mathematics#Explicitness|mathematical notation]] <math>\sqrt[x]{y}</math>. Root shares the [[glyph]] <source lang=apl inline>√</syntaxhighlight> with the monadic function [[Square Root]], which is the same as Root with the default left argument of 2. Root is defined in [[J]], [[NARS2000]], [[dzaima/APL]], and [[Extended Dyalog APL]].
