How to get abs() of an mpz in GMPY2?

Question

I need to get the absolute value of an mpz object in GMPY2 but I cannot find any function like abs(). How can this be done?

Answer 1

mpz objects provide __abs__, and so the ordinary abs works:

>>> gmpy2.mpz(3)
mpz(3)
>>> abs(gmpy2.mpz(3))
mpz(3)
>>> gmpy2.mpz(-3)
mpz(-3)
>>> abs(gmpy2.mpz(-3))
mpz(3)
