Test gmpy2_minus.c
==================

>>> from gmpy2 import mpz, mpq, mpfr, mpc
>>> import gmpy2
>>> from fractions import Fraction

>>> ctx = gmpy2.get_context()
>>> ctx.minus(mpz(5))
mpz(-5)
>>> ctx.minus(mpq(4,5))
mpq(-4,5)
>>> ctx.minus(mpfr(4,5))
mpfr('-4.0')
>>> ctx.minus(mpfr('inf'))
mpfr('-inf')
>>> ctx.minus(mpc(15,3))
mpc('-15.0-3.0j')
>>> ctx.minus(65)
mpz(-65)
>>> ctx.minus(5.5)
mpfr('-5.5')
>>> ctx.minus(Fraction(2,3))
mpq(-2,3)
>>> ctx.minus(complex(15,3))
mpc('-15.0-3.0j')
>>> - mpc(5,5)
mpc('-5.0-5.0j')
