In gmpy2, I added support for MPFR and MPC and one of the goals was to
make gmpy2 follow existing Python conventions as much as possible.
gmpy2.sqrt now returns an mpfr type and gmpy2.isqrt returns the
integer square root.
The mpmath repository includes a couple fixes for gmpy2. For example,
one of fixes in mpmath is
if BACKEND == 'gmpy':
if gmpy.version() >= "2":
isqrt_small = isqrt_fast = isqrt = gmpy.isqrt
sqrtrem = gmpy.isqrt_rem
else:
isqrt_small = isqrt_fast = isqrt = gmpy.sqrt
sqrtrem = gmpy.sqrtrem
I've follwed a similar approach in sympy.
