Possible collision with #28641 which refers to the same ask.sagemath.org question. |

Replying to @sagetrac-tmonteil:
Yes, but the solutions are orthogonal to each other. In other words: after applying this branch, #28641 solves a different problem. |

some failing doctests in src/sage/functions/generalized.py and src/sage/functions/exp_integral.py |

There are unfortunately more problems. In particular, |

I'm afraid my approach won't work, because FriCAS distinguishes between Put differently, the complex unit
I tend towards option 1., but I am not sure at all. |

Unfortunately, #18036 breaks this. |

I believe you can simplify - if (isinstance(obj, NumberFieldElement_quadratic) and
- obj.parent() is GaussianField()):
+ if isinstance(obj, NumberFieldElement_gaussian): I probably would also add a test that includes |

Thank you. LGTM. |

This ticket modifies the FriCAS interface so that symbolic ring elements are always converted to FriCAS
Expression Integer
orExpression Complex Integer
, depending on whether the complex unit appears. Doing so, we fix the failure below.see https://ask.sagemath.org/question/48431/why-this-integral-fail-using-fricas-algorithm/
