ModInverse in perl

Hi,

I am trying to calculate inverse modulus of a mod n ie.,

a ^ -1 mod n.

Is there a function in Perl that does this for me. If not, can someone help me with the code?

Thanks in advance.

Thanks,
Sundeep.

NAME
File::Find::Rule::Perl - Common rules for searching for Perl things SYNOPSIS
use File::Find::Rule (); use File::Find::Rule::Perl (); # Find all Perl files smaller than 10k my @files = File::Find::Rule->perl_file ->size('<10Ki') ->in('dir'); # Locate all the modules that PAUSE will index my @mod = File::Find::Rule->no_index ->perl_module ->in('My-Distribution'); DESCRIPTION
I write a lot of things that muck with Perl files. And it always annoyed me that finding "perl files" requires a moderately complex File::Find::Rule pattern. File::Find::Rule::Perl provides methods for finding various types Perl-related files, or replicating search queries run on a distribution in various parts of the CPAN ecosystem. METHODS
perl_module The "perl_module" rule locates perl modules. That is, files that are named "*.pm". This rule is equivalent to "->"file->name( '*.pm' )> and is included primarily for completeness. perl_test The "perl_test" rule locates perl test scripts. That is, files that are named "*.t". This rule is equivalent to "->"file->name( '*.t' )> and is included primarily for completeness. perl_installer The "perl_installer" rule locates perl distribution installers. That is, it locates "Makefile.PL" and "Build.PL" files. perl_script The "perl_script" rule locates perl scripts. This is any file that ends in .pl, or any files without extensions that have a perl "hash-bang" line. perl_file The "perl_file" rule locates all files containing Perl code. This includes all the files matching the above "perl_module", "perl_test", "perl_installer" and "perl_script" rules. no_index # Provide the rules directly $rule->no_index( directory => [ 'inc', 't', 'examples' ], file => [ 'Foo.pm', 'lib/Foo.pm' ], ); # Provide a META.yml to use $rule->no_index( 'META.yml' ); # Provide a dist root directory to look for a META.yml in $rule->no_index( 'My-Distribution' ); # Automatically pick up a META.yml from the target directory $rule->no_index->in( 'My-Distribution' ); The "no_index" method applies a set of rules as per the no_index section in a "META.yml" file.
