{{Built-in|Greater than|<nowiki>></nowiki>}} is a [[comparison function]] which tests whether the left [[argument]] is [[Tolerant comparison|tolerantly]] greater than and not equal to the right argument, returning 1 if this is the case and 0 otherwise. It is the [[Not|negation]] of [[Less than or Equal to]] (<source lang=apl inline>≤</source>). | {{Built-in|Greater than|<nowiki>></nowiki>}} is a [[comparison function]] which tests whether the left [[argument]] is [[Tolerant comparison|tolerantly]] greater than and not equal to the right argument, returning 1 if this is the case and 0 otherwise.
