Test hash() behavior
====================

This test is only applicable for Python 3.2 and later.

    >>> import gmpy2
    >>> from gmpy2 import mpz, mpq, mpfr
    >>> from decimal import Decimal
    >>> gmpy2.set_context(gmpy2.context())


    >>> hash(mpfr('123.456')) == hash(float('123.456'))
    True
    >>> hash(mpfr('123.5')) == hash(float('123.5'))
    True
    >>> hash(mpfr('0')) == hash(float('0'))
    True
    >>> hash(mpfr('1')) == hash(float('1'))
    True
    >>> hash(mpfr('2')) == hash(float('2'))
    True
    >>> hash(mpfr('-1')) == hash(float('-1'))
    True
    >>> hash(mpfr('Inf')) == hash(float('Inf'))
    True
    >>> hash(mpfr('-Inf')) == hash(float('-Inf'))
    True
    >>> hash(mpfr('-0')) == hash(float('-0'))
    True
    >>> hash(mpfr('NaN')) == hash(float('NaN'))
    True
    >>> hash(mpfr('123.456')) == hash(Decimal('123.456'))
    False
    >>> hash(mpfr('123.5')) == hash(Decimal('123.5'))
    True
    >>> hash(mpq(123456,1000)) == hash(Decimal('123.456'))
    True
    >>> hash(mpz(123)) == hash(Decimal(123))
    True
