Misc fixes #731

skirpichev · 2023-10-16T04:41:29Z

remove obsoleted note on upgrade
rephrase note on gmpy2 detection
fix mpc() constructor to be compatible with complex(), closes mpc() constructor should be compatible with complex() #730
add note about new int/str conversion limits, closes Document/(disable?) new int/str conversions limits (in CPython 3.11+ and older bugfix releases) #716
avoid extra type-cast (int -> MPZ) in str_to_man_exp()
fix disagreement fp.pow vs mp.pow, closes Evaluating limits of hyperu function #512, closes Unexpected return from mp.hermite when evaluating limit #523
add mpf.as_integer_ratio() method, closes Interoperability with gmpy2 #417
raise OverflowError for infs in to_rational
support construction of mpf from Decimal objects
simplify _mpf.__new__()

gmpy2 has fix for aleaxit/gmpy#381 only in the development version, so I have added simple workaround for this.

Handle special values as in the ISO C99 and IEEE 754 standards for the pow function. Closes mpmath#523 Closes mpmath#512

Closes mpmath#417. I think we can't do better: e.g. if we provide the mpf._mpfr_ property - then in expressions like mpq(1,2)+mpf(1.0) - second operand (and the whole expression) will be promoted to mpfr. Also this corrects to_rational() private function to return a pair of integers with same type.

And more tests
