{{Built-in|Logarithm|⍟}}, or '''Log''', is a [[dyadic]] [[scalar function]] which computes the [[wikipedia:logarithm|logarithm]] of the two [[argument|arguments]]. More precisely, <source lang=apl inline>X⍟Y</source> computes how much [[power]] of X equals Y, i.e. the value of R that satisfies <source lang=apl inline>Y=X*R</source>. Logarithm shares the [[glyph]] <source lang=apl inline>⍟</source> with the monadic arithmetic function [[Natural Logarithm]]. | {{Built-in|Logarithm|⍟}}, or '''Log''', is a [[dyadic]] [[scalar function]] which computes the [[wikipedia:logarithm|logarithm]] of the two [[argument|arguments]].
