How do you find the remainder without modulus operator?

How do you find the remainder without modulus operator?

C program to find the remainder without using modulo operator

1. First read the number and divisor as entered by the user.
2. Keep subtracting the divisor from the number and set the value to the number till the number become less than divisor.
3. If the number becomes less than divisor, it should be the required remainder.

How do you do Bitwise division?

The standard way to do division is by implementing binary long-division….In essence, if you’re doing Q = N/D :

1. Align the most-significant ones of N and D .
2. Compute t = (N – D); .
3. If (t >= 0) , then set the least significant bit of Q to 1, and set N = t .
4. Left-shift N by 1.
5. Left-shift Q by 1.
6. Go to step 2.

How do you get a remainder?

Work the division in your calculator as normal. Once you have the answer in decimal form, subtract the whole number, then multiply the decimal value that’s left by the divisor of your original problem. The result is your remainder. For example, divide 346 by 7 to arrive at 49.428571.

Is XOR a division?

The process of modulo-2 binary division is the same as the familiar division process we use for decimal numbers. Just that instead of subtraction, we use XOR here. In each step, a copy of the divisor (or data) is XORed with the k bits of the dividend (or key).

How do Bitwise Operators divide by 3?

Algorithm

1. Take a number num, sum = 0.
2. while(num>3), shift the number left by 2 bits and sum = add(num >> 2, sum). Create a function add(x, y) for adding two number by bitwise opreator.
3. Take bitwise AND of num with 3.
4. After terminating while loop print the value of sum which give final result .

How can I do division without using operator?

In order to perform division operation without using ‘/’ operator we followed the approach, in which we count the number of successful or complete number of substraction of num2 from num1. Where num1 is the number to be divided and num2 is the number from which we have to divide num1. Attention reader! Don’t stop learning now.

How to divide two integers without division and Division?

Divide two integers without using multiplication, division and mod operator. Given a two integers say a and b. Find the quotient after dividing a by b without using multiplication, division and mod operator. Example: Approach : Keep subtracting the divisor from dividend until dividend becomes less than divisor.

Which is the correct way to do Division and multiplication?

Use left shift operator “<<” to do multiplication. If you left shift a number by 1, then it is equal to multiply that number by 2. Use right shift operator “>>” to do division. If you right shift a number by 1, then it is equal to the division that number by 2.

How is the division of two numbers solved?

We know that divisions can be solved by repeatedly subtracting the divisor from the dividend until it becomes less than the divisor. The total number of times the repeated subtraction is carried out is equal to the quotient. This approach is demonstrated below in C, Java, and Python:
