四舍五入,变量来自Python 3中的.txt和额外

if op in ["/"]:
    # rounding does not rounds half up so I imported a module
    from decimal import Decimal, ROUND_HALF_UP, ROUND_HALF_DOWN
    Decimal(str(answer)).quantize(Decimal("1.11"), rounding=ROUND_HALF_UP)
    Decimal(str(given_answer)).quantize(Decimal("1.11"), rounding=ROUND_HALF_UP)
print("correct {}".format(answer, ".2f"))

49//34=?1.44

如果真实答案是3.55865465,我希望它的正确答案为3.56。我做错了什么?
