This article mainly explains "what is the realization of division and remainder in Java". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the realization of division and remainder in Java".

The two concepts of modular operation and remainder operation overlap but are not completely consistent. The main difference is that the operation is different when dividing negative integers.

For the shaping number aforme b, the methods of modular operation or remainder operation are:

1. Find the integer quotient c = a / b

2. Calculation module or remainder r = a-c * b.

The modular operation and the remainder operation are different in the first step:

When the c value is taken, the remainder operation is rounded to 0 direction, while the modular operation is rounded to negative infinity when taking c value.

The meaning of the operator% varies from environment to environment. Cmax is complementary to Java, and python is a module.

The rules of Java remainder operation are as follows:

A% b = a-(a bank b) * b

Let's look at a piece of code first:

Public class Division_remainder {public static void main (String [] args) {int a = 13 / 5; int b = 13% 5; int c = 5 / 13; int d = 5% 13; int e = 13 /-5; int f =-13 / 5; int h =-13% 5; int j = 13%-5; System.out.println (a + "," + b); System.out.println (c + "," + d); System.out.println (e + "," + f) System.out.println (h + "," + j);}

The result is:

2, 3, 3, 5, 5, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 5, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4 and 3

Let's make another analysis:

A = 13 / 5, a = 2, which is actually 13 / 5 in mathematics, and the result is 2.

B = 13% 5 and b = 3, which is also a mathematical operation, and the remainder is 3.

C = 5 / 13 c = 0, because the divisor is less than the divisor, the result can be regarded as 0.x, but the int type is an integer type, so the result is only 0.

D = 5% 13 and d = 5, mathematically stipulates that if the divisor is smaller than the divisor, the quotient is 0, the remainder is the divisor itself.

Needless to say, e and f both turn out to be-2.

But how can h and j be a-3, because the symbol of the remainder operation is determined by the first Operand,-13% 5 results in-3, and 13%-5 results in 3.
