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:
#!/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:
#!/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
