How do you find the number of digits in a product of two numbers?

How do you find the number of digits in a product of two numbers?

Naive Approach: Multiply the two numbers and then by using looping construct find the number of digits in the product. Take the absolute value of the product for finding the number of digits.

What is the formula of product of two numbers?

If you are asked to work out the product of two or more numbers, then you need to multiply the numbers together. If you are asked to find the sum of two or more numbers, then you need to add the numbers together. Below, we will work through several examples together. “Product” means multiply.

Logic to count number of digits in an integer

  1. Input a number from user.
  2. Initialize another variable to store total digits say digit = 0 .
  3. If num > 0 then increment count by 1 i.e. count++ .
  4. Divide num by 10 to remove last digit of the given number i.e. num = num / 10 .
  5. Repeat step 3 to 4 till num > 0 or num !=

How many digits is a product number?

How do I count the number of digits in Excel?

To use the function, enter =LEN(cell) in the formula bar and press Enter. In these examples, cell is the cell you want to count, such as B1. To count the characters in more than one cell, enter the formula, and then copy and paste the formula to other cells.

How many digits are there in the product of 2 101 and 5 99?

We’ll have 99 zeroes+ 4 at the beggining, so 100 digits.

What will be the product of 68 by itself?

What is called the total number of digits used in number system?

The total number of digits used in a number system is called its base or radix. The base is written after the number as subscript such as 51210.

How do you find the product of digits?

General Algorithm for product of digits in a given number: Get the rightmost digit of the number with help of remainder ‘\%’ operator by dividing it with 10 and multiply it with product. Divide the number by 10 with help of ‘/’ operator. Print or return the product.

What is the product of the digits mean?

In maths the product of two numbers is the result you get when you multiply them.

What is the product of a 3-digit and 2-digit number?

As a proof , consider a 3-digit number and a 2-digit number. If both the numbers are greater than 10 x 10^ [no of digits in them (M and N)] then the product is guaranteed to be a M+N digit number. If both do not satisfy this condition, then the product depends on the actual values of the multiplicands.

How do you calculate the number of digits of a number?

To calculate the number of digits, we have to calculate the total number of digits required to write at ones, tens, hundredths …. places of the number . Consider n = 13, so digits at ones place are 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3 and digits at tens place are 1, 1, 1, 1 .

What is the product of m digit and n digit?

If you multiply a M-digit number with an N-digit number, you will either get an M+N-1 or an M+N digit number as the product. Whether it is an M+N-1 or an M+N digit answer is determined by the numerical value of the multiplicands. As a proof , consider a 3-digit number and a 2-digit number.

What is the total number of digits we have to write?

Hence, total number of digits we have to write are 234 ( 234 – 1 + 1 ) + 225 ( 234 – 10 + 1 ) + 135 ( 234 – 100 + 1 ) = 594 . So, basically we have to decrease 0, 9, 99, 999 … from n to get the number of digits at ones, tens, hundredths, thousandths … places and sum them to get the required result.
