Hi!

I have a Perl program that uses the Math::Trig module. The program works fine (apparently) but I get this warning when I execute it:


Prototype mismatch: sub main::tan (;@) vs none at /usr/lib/perl5/5.10.0/Exporter.pm line 67, <DATA> line 387. at hogg.pl line 14


actually, line 14 is the module call:


use Math::Trig;


I reinstalled both Math::Trig and Exporter but the issue persists. Any thoughts?

UPDATE: Sorry forgot to add the the mentioned warning line is only the first, and that a warning message appears for all and each one of the methods:
