{{Built-in|Ceiling|⌈}} is a [[monadic]] [[scalar function]] which gives the [[wikipedia:floor and ceiling functions|ceiling]] of a real number, i.e. the least integer greater than or equal to the given value. This operation is also known as '''round up'''. Ceiling shares the [[glyph]] <source lang=apl inline>⌈</source> with the dyadic arithmetic function [[Maximum]]. | {{Built-in|Ceiling|⌈}} is a [[monadic]] [[scalar function]] which gives the [[wikipedia:floor and ceiling functions|ceiling]] of a real number, i.e. the least integer greater than or equal to the given value.
