APL was originally conceived as an improved notation for mathematics, unifying a variety of fields and concepts. This effort is sometimes portrayed as a failure for not being universally adopted wholesale, but some of its ideas did influence popular usage, including the adoption of APL's ⌊ (floor) and ⌈ (ceiling) symbols, as well as those names for the operations.
