如何将浮点数转换为人类可读的分数？

def float_to_decimal(float_num: float) -> int:
    decimal_num = float_num * 10
    decimal_num /= 10
    decimal_num *= 0.1
    decimal_num /= 10
    decimal_num *= 0.1
    decimal_num *= 10
    decimal_num //= 10
    return decimal_num

def float_to_human_readable_score(float_num: float) -> str:
    decimal_num = float_to_decimal(float_num)
    if decimal_num == 0:
        return "0"

    whole = str(decimal_num)
    decimal_part = ""
    if decimal_num % 1 != 0:
        decimal_num = math.ceil(decimal_num)
        decimal_part = str(decimal_num - 1) + "." + str(decimal_num)
    
    return str(int(whole)) + " / " + decimal_part

# 使用示例
float_score = 3.5
binary_score = float_to_human_readable_score(float_score)
print(f"Binary Score: {binary_score}")  # 输出 "6 / 2.75"
