What is an example of trailing zero?
In decimals, this idea of zeros that don’t add value to a number can be extended to trailing zeros. A trailing zero is any zero that appears to the right of both the decimal point and every digit other than zero. In this example, 34.8000 means 30 + 4 + 8/10 + 0 + 0 + 0.
How do you count trailing zeros in Python?
Take the length of the string value of what you’re checking. Trim off trailing zeros from a copy of the string. Take the length again, of the trimmed string. Subtract the new length from the old length to get the number of zeroes trailing.
What is the number of trailing zeros in 123 factorial?
0 trailing zeros
123 has 0 trailing zeros and is not divisible by 10. The highest power of ten it is divisible by is 1 0 0 = 1. 10^0=1.
How many trailing zeros are there in 30 factorial?
There are seven zeros in the end, and two in the middle. By sheer computation, this is nine zeros in 30!.
What is a number with 99 zeros called?

How to count the trailing zeros in integer?
You could just: 1 Take the length of the string value of what you’re checking. 2 Trim off trailing zeros from a copy of the string. 3 Take the length again, of the trimmed string. 4 Subtract the new length from the old length to get the number of zeroes trailing.
How to count number of trailing zeros in binary representation?
Take an integer num as input. Function trailing_zeroes (int num) takes num and returns the count of number of trailing zeros in Binary representation of a number using Bitset. Take the initial count as 0. Set it with num as arr |=num. Traverse arr using for loop from i=0 to i<64.
How to count trailing 0s in factorial of N?
A simple method is to first calculate factorial of n, then count trailing 0s in the result (We can count trailing 0s by repeatedly dividing the factorial by 10 till the remainder is 0). The above method can cause overflow for a slightly bigger numbers as factorial of a number is a big number (See factorial of 20 given in above examples).
