Perl | Math::BigInt->from_oct() method

Math::BigInt module in Perl provides objects that represent integers with arbitrary precision and overloaded arithmetical operators.
from_oct() method of Math::BigInt module is used to convert the octal number passed as input to its corresponding decimal number.

Syntax: Math::BigInt->from_oct()
Parameter: input octal number to be converted
Returns: a corresponding decimal number of the passed octal number

Example 1:

perl

#!/usr/bin/perl

# Import Math::BigInt module
use Math::BigInt;

# Converting from octal to decimal
$x = Math::BigInt->from_oct("0345");
print("$x\n");

# Converting from octal to decimal
$x = Math::BigInt->from_oct("_443");
print("$x\n");

Output:

229
291

Example 2:

perl

#!/usr/bin/perl

# Import Math::BigInt module
use Math::BigInt;

# Converting negative number
# from octal to decimal
$x = Math::BigInt->from_oct("-0345");
print("$x\n");

# Converting negative number
# from octal to decimal
$x = Math::BigInt->from_oct("-_443");
print("$x\n");

Output:

-229
-291
