(CAV) A disk driving scheme in which the angular velocity of the disk is kept constant. This means that the linear velocity of the disk is larger when reading or writing the outer tracks. The disadvantage of this technique is that the read/write speed varies from track to track. However, as mechanical stability puts an upper limit on the angular velocity (and not the linear velocity) this allows the full potential of the drive to be used.
- Constant applicative form
functional programming (CAF) A supercombinator which is not a lambda abstraction. This includes truly constant expressions such as 12, (+ 1 2), [1, 2, 3] as well as partially applied functions such as (+ 4). Note that this last example is equivalent under eta abstraction to \ x . + 4 x which is not […]
- Constant de Rebecque
[kawn-stahn duh ruh-bek] /kɔ̃ˈstɑ̃ də rəˈbɛk/ noun 1. Henri Benjamin [ahn-ree ban-zha-man] /ɑ̃ˈri bɛ̃ ʒaˈmɛ̃/ (Show IPA), (Benjamin Constant) 1767–1830, French statesman and author, born in Switzerland.
noun 1. a dollar valued according to its purchasing power in an arbitrarily set year and then adjusted for price changes in other years so that real purchasing power can be compared by giving prices as they would presumably be in the base year.
- Constant folding
compiler A compiler optimisation technique where constant subexpressions are evaluated at compile time. This is usually only applied to built-in numerical and boolean operators whereas partial evaluation is more general in that expressions involving user-defined functions may also be evaluated at compile time.
