Math::BigInt module in Perl provides objects that represent integers with arbitrary precision and overloaded arithmetical operators.
digit() method of
Math::BigInt module is used to get
nth digit of the given number counting from right. To get the digit from the left side we need to specify
n as negative.
Syntax: Math::BigInt->digit($n)
Parameter:
$n: An integer value denoting the digit to be extracted.
Returns: an integer value which represents the nth digit of the given number counting from the right side.
Example 1: use of
Math::BigInt->digit() method
Output:
4th digit in 7821593604 is 9.
6th digit in 7821593604 is 1.
Example 2: use of
Math::BigInt->digit() method to get
nth digit from left
Output:
4th digit from left in 7821593604 is 1.
6th digit from left in 7821593604 is 9.
Example 3: use of
Math::BigInt->digit() method to calculate sum of digits of a number
Output:
Sum of digits in 7821593604 is 45.
