Math::BigInt module in Perl provides objects that represent integers with arbitrary precision and overloaded arithmetical operators.
is_odd() method of Math::BigInt module is used to check whether a number stored as BigInt object is an odd number or not.
Syntax: Math::BigInt->is_odd() Parameter: None Returns: true if the number stored in BigInt object is an odd number, otherwise returns false.Example 1: Use of
Math::BigInt->is_odd() method
#!/usr/bin/perl
# Import Math::BigInt module
use Math::BigInt;
# Value of n
$n = '89123751682746';
# Create BigInt object
$x = Math::BigInt->new($n);
# Check if the number stored
# in BigInt object is
# an odd number or not
$isOdd = $x->is_odd();
if ($isOdd)
{
print "$n is an odd number\n";
}
else
{
print "$n is not an odd number\n";
}
# Value of n
$n = '6348762649837957979685908708650797587783';
# Create BigInt object
$x = Math::BigInt->new($n);
# Check if the number stored
# in BigInt object is
# an odd number or not
$isOdd = $x->is_odd();
if ($isOdd)
{
print "$n is an odd number\n";
}
else
{
print "$n is not an odd number\n";
}
Output:
Example 2: Use of 89123751682746 is not an odd number 6348762649837957979685908708650797587783 is an odd number
Math::BigInt->is_odd() method to check whether Octal number is an odd number in decimal or not.
#!/usr/bin/perl
# Import Math::BigInt module
use Math::BigInt;
# Octal number represented as string
$octal = 726746425;
# value of octal '726746425' is
# 123456789 in decimal number system
# Create BigInt object
$x = Math::BigInt->from_oct($octal);
# Check whether the Octal
# number stored in BigInt object
# is an odd number or not
# using Math::BigInt->is_odd() method
$isOdd = $x->is_odd();
if($isOdd)
{
print "$octal (in octal) is an odd number in decimal";
}
else
{
print "$octal (in octal) is not an odd number in decimal";
}
Output:
Example 3: Use of 726746425 (in octal) is an odd number in decimal
Math::BigInt->is_odd() method to check whether a hexadecimal is an odd number in decimal or not.
#!/usr/bin/perl
# Import Math::BigInt module
use Math::BigInt;
# Hexadecimal number represented as string
$hex = 'Ox112210F4B16C1CB1';
# Hexadecimal value '0x112210F4B16C1CB1' is
# 1234567890987654321 in decimal number system
# Create BigInt object
$x = Math::BigInt->new($hex);
# Check whether the hexadecimal
# number stored in BigInt object
# is an odd number or not
# using Math::BigInt->is_odd() method
$isOdd = $x->is_odd();
if($isOdd)
{
print "$hex (in hexadecimal) is an odd number in decimal";
}
else
{
print "$hex (in hexadecimal) is not an odd number in decimal";
}
Output:
Ox112210F4B16C1CB1 (in hexadecimal) is an odd number in decimal
