%和 // 运算符实现了 remainder 和 divide-integer 操作(分别),如规范中所述。十进制对象通常不能与浮点数或 fractions.Fraction 实例在算术运算中结合使用:例如,尝试将 Decimal 加到 float ,将引发 TypeError。 但是,可以使用 Python 的比较运算符来比较 Decimal 实例 x 和另一个数字 y 。 这样可以避免在对...
英文: print number1 floor divide by number2, will divide 19 by 5, and ignore any decimals, and round down the result from 3.8 to 3 print(-nubmer1 // number2) # output: -4 ## 打印输出 -number1 向下取整 number2 时,会将结果从-3.8向下舍入到-4. 英文:print negative number1 floor...
This method is commonly used in mathematical applications, for example in accounting. It is the one generally taught in elementary mathematics classes.[citation needed]This method is also known asAsymmetric Arithmetic RoundingorRound-Half-Up (Asymmetric Implementation) 1.

However, if you were to divide them by hand or use a tool like WolframAlpha, then you’d end up with those fifty-five decimal places you saw earlier.There is a way to find close approximations of your fraction that have more down-to-earth values. You can use .limit_denominator(), ...

快速排序使用分治法(Divide and conquer)策略来把一个序列(list)分为两个子序列(sub-lists)。 步骤 从数列中挑出一个元素,称为"基准"(pivot), 重新排序数列,所有元素比基准值小的摆放在基准前面,所有元素比基准值大的摆在基准的后面(相同的数可以到任一边)。在这个分区结束之后,该基准就处于数列的中间位置。这...
