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
Apache2::FilterRec - Perl API for manipulating the Apache filter record Synopsis use Apache2::Filter (); use Apache2::FilterRec (); my $frec = $filter->frec; print "filter name is:", $frec->name; Description "Apache2::FilterRec" provides an access to the filter record structure. The "Apache2::FilterRec" object is retrieved by calling "frec()": $frec = $filter->frec; API
"Apache2::FilterRec" provides the following functions and/or methods: "name" The registered name for this filter $name = $frec->name(); obj: $frec ( "Apache2::FilterRec object" ) ret: $name (string) since: 2.0.00 mod_perl filters have four names: modperl_request_output modperl_request_input modperl_connection_output modperl_connection_input You can see the names of the non-mod_perl filters as well. By calling "$filter->next->frec->name" you can get the name of the next filter in the chain. Example: Let's print the name of the current and the filter that follows it: use Apache2::Filter (); use Apache2::FilterRec (); for my $frec ($filter->frec, $filter->next->frec) { print "Name: ", $frec->name; } See Also mod_perl 2.0 documentation.
