Re: Tax rounding error in 1.2.4

[..hidden..]

Thanks Chris,

I've been futzing around with perl (I feel unclean).  I was wondering  
if you had considered the Math::Currency module for currency  
calculations?  I've been having a go myself, but I'm not sure how to  
access the transaction currency from   Taxes::Simple.

I use perl very rarely and only under threat of torture...

Cheers,
Richard
