General ⇒ fp | Strange Interaction with Bibliography

[aipe]

Hi,

When trying to use \FPeval within the {thebibliography} environment, I noticed that the variable used to hold the result of the \FPeval computation gets reset outside the {thebibliography} environment to its initial value. This is demonstrated by the following example code.

Code: Select all

\documentclass[9pt,a4paper,twoside]{article}

% Do not make all pages exactly the same size.
\raggedbottom

% Use xifthen conditional branch package
\usepackage{xifthen}

% Unicode stuffs
\usepackage[mathletters]{ucs}
\usepackage[frenchb,english]{babel}
\usepackage[latin1]{inputenc}

\usepackage{a4wide}
\usepackage{color}

\usepackage{amsfonts,amsmath,amsthm}
\usepackage{amssymb,amscd,amstext}
\usepackage{latexsym}
\usepackage{exscale}
\usepackage{euscript}

% Use other fonts than default
\usepackage[slantedGreek]{mathpazo}
%\usepackage{times}

% Table formatting as done in books
%\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{colortbl}

% Make arithmetic with variables
\usepackage{calc}

% Evaluate arithmetic expression
\usepackage[debug]{fp}

% Allow margin note in floats
\usepackage{marginnote}

% Allow better treatment of marginal notes
\usepackage{mparhack}

% Fancy headers & footers
\usepackage{fancyhdr}
\pagestyle{plain}


% Bibliography management : modified style for headers to be not in uppercase
\usepackage[comma,numbers,sort&compress]{natbib}

% Multiple bibliographies
\usepackage{multibib}
\newcites{phd,peerfirst,peernotfirst,peernotisi,report,poster,talk}{X,X,X,X,X,X,X}

% Allow optional text
\usepackage[weight]{optional}
\opt{weight}{
\edef\peerfirst{0}
}
\opt{weight}{
\edef\peernotfirst{0}
}
\opt{weight}{
\edef\pubtotal{0}
}

\newcommand{\cpeerfirst}[1]{\opt{weight}{\marginpar[\itshape\small\raggedleft#1]{\itshape\small\raggedright#1}\FPeval\peerfirst{clip(peerfirst+(35))}}}


\title{\textsc{Curriculum Vitae}}

\date{}

\opt{weight}{\marginpar[\itshape\small\raggedleft Total : \FPprint\peerfirst]{\itshape\small\raggedright Total : \FPprint\peerfirst}}

\end{thebibliography}
\endgroup

\opt{weight}{\marginpar[\itshape\small\raggedleft Total : \FPprint\peerfirst]{\itshape\small\raggedright Total : \FPprint\peerfirst}}
\FPeval\pubtotal{clip(pubtotal+peerfirst)}

\end{document}

I would expect the value of the second Total to be 70 as for the first and not 0.

Am I doing something wrong ?

Many thanks,


Alessandro.
