  • Ticket #18333 – Description

    v5 v6  
    55- #18334: implement `unique_sign` and `unique_trunc` on interval field elements
    66- #18337: implement `real` and `imag` on real intervals
     7- #17830: consider the natural order induced from `RR` for number fields with real embedding
    78
    8 Actual tasks:
     9Tasks in `AA/QQbar`:
    910- #18303: better comparisons
    1011- #17886 and #18242: faster qqbar operations using resultants
    1112- #15600: exactification is slow in `do_polred`
    1213- #16222, #18122: enhanced minpoly
    13 - use firstly interval arithmetic for `sign`/`floor`/`ceil`/`trunc`/`round`
     14- use firstly interval arithmetic for `sign`/`floor`/`ceil`/`trunc`/`round` instead of the `_floor_ceil` helper
    1415- remove the following methods from `ANDescr`:
    1516   - `rational_value`
     
    1718   - `is_exact`
    1819- fusion `ANRoot` and `ANRootOfUnity` within `ANExtension`
     20- remove redundancy between the unary operators `norm`, `abs`, `real`, `imag` and `conjugate`
    1921- enhanced `sage_input` for `ANExtension`
    2022- better powering (`__pow__`) using `ANExtension` and fix convention for powering in `AA` vs `QQbar`
    2123- reimplement `_real_refine_interval` without these ugly dictionaries (see also #17895)
    22 - make number field elements compare themselves and use that
     24- use directly embedded number fields in `AlgebraicGenerator`
