It supports real and complex numbers, polynomials, power series, matrices, and evaluation of many transcendental functions. All operations are done with automatic, rigorous error bounds. </longdescription> <upstream> <remote-id type="github">fredrik-johansson/arb</remote-id> </upstream> </pkgmetadata>
