    1 Provide the order from RR for real quadratic number field. The current implementation does
     1The order of quadratic field is not induced from the order of RR and CC (when there is an embedding). More precisely we have
    22{{{
    33sage: K.<sqrt2> = NumberField(x^2 - 2, 'sqrt2', embedding=1.4142)
     
    55False
    66}}}
     7which is not compatible with the order of RR and
     8{{{
     9sage: K.<i> = QuadraticField(-1)
     10sage: i > 1
     11True
     12sage: 1 > i
     13True
     14}}}
     15which is not compatible (!) with the order of CC.

    8 There is a patch for quadratic field. Another one is comming for general number fields. Note that this patch is partly a duplicate because of #7160.
     17There is a patch for quadratic field. Another will come for general number fields. Note that this patch is partly a duplicate because of #7160. The modifications for the order on complex number field modify the behavior of many commands (output order).
