Arb is an implementation of ball arithmetic, also known as mid-rad interval
|
|
arithmetic. Ball arithmetic is an extension of floating-point arithmetic in
|
|
which an error bound is attached to each variable. This allows computing
|
|
rigorously with real and complex numbers.
|
|
|
|
With plain floating-point arithmetic, the user must do an error analysis to
|
|
guarantee that results are correct. Manual error analysis is time-consuming and
|
|
bug-prone. Ball arithmetic effectively makes error analysis automatic.
|
|
|
|
Arb is designed for computer algebra and computational number theory, but may be
|
|
useful in any area demanding reliable or precise numerical computing. Arb scales
|
|
seamlessly from tens of digits up to billions of digits. Efficiency is achieved
|
|
by low level optimizations and use of asymptotically fast algorithms.
