2024年8月23日 · Division (/) Divides left hand operand by right hand operand. Example: 4 / 2 = 2. Floor division (//) The division of operands where the result is the quotient in which the digits after the decimal point are removed. But if one of the operands is negative, the result is floored, i.e., rounded away from zero (towards negative infinity):

2017年5月30日 · According to Java terminology, the question of "Truncated Division" vs "Floored division" is best answered by the javadoc of RoundingMode: DOWN Rounding mode to round towards zero. Never increments the digit prior to a discarded fraction (i.e., truncates). Note that this rounding mode never increases the magnitude of the calculated value. FLOOR

2015年7月16日 · Floor division works in Python the way it's mathematically defined. x // y == math.floor(x/y) In other words x // y is the largest integer less than or equal to x / y

First, perform integer division, which is similar to normal division, except any fractional number (a.k.a. remainder) is discarded: 16 / 6 = 2 Then, multiply the result of the above division (2) with our divisor (6): 2 * 6 = 12 Finally, subtract the result of the above multiplication (12) from our dividend (16): 16 - 12 = 4

2009年10月8日 · In Python 3, they made the / operator do a floating-point division, and added the // operator to do integer division (i.e., quotient without remainder); whereas in Python 2, the / operator was simply integer division, unless one of the operands was already a floating point number. In Python 2.X:

2020年10月28日 · If you're using integers in the division and you cast the solution to another integer (by storing the result in another integer variable), the division is already a floor division: int a = 5; int b = 2; int c = 5/2; System.out.println(c); >> 2 As khelwood stated, it also works with negative values but the rounding is done towards 0.

2019年6月17日 · floor division is the number of times the hand has completed a cycle; Example 1. In the first cycle when the hand points at 4 the modulus is 4 but the floor division is 0. 4 % 12 # returns 4 4 // 12 # returns 0 Example 2. In the second cycle when the hand points at 4 the modulus is still 4 but the floor division is now 1

2013年7月8日 · As you say, the % sign is used to take the modulus (division remainder). In w3schools' JavaScript Arithmetic page we can read in the Remainder section what I think to be a great explanation. In arithmetic, the division of two integers produces a quotient and a remainder.

2012年7月26日 · While I agree with BlueTrin that %% is pretty standard, I have a suspicion %/% may have something to do with the sort of operator definitions I showed above - perhaps it was easier to implement, and makes sense: %/% means do a special sort of division (integer division)

2016年3月2日 · Meaning that some division statements return a reasonable approximation of division ("true division") and others return the floor ("floor division"). Starting in Python 3.0, true division is specified by x/y, whereas floor division is specified by x//y. The from __future__ import division directive forces the use of Python 3.0 style division.
