Re: pgfcalendar, contatore ed errore dimension too large

Ho risolto attivando la libreria [tt]fpu[/tt] di TikZ e utilizzando questo codice:
`\newcount\datax
\newcount\datamin
\newcount\deltadata
\pgfcalendardatetojulian{1920-01-01}{\datamin}
\pgfcalendardatetojulian{2013-12-01}{\deltadata}
\advance\deltadata -\datamin\relax
\newcommand\tfdata[1]{
\pgfcalendardatetojulian{#1}{\datax}
\advance\datax -\datamin\relax
\pgfkeys{/pgf/fpu=true,pgf/fpu/output format=fixed}
\pgfmathparse{\datax/\deltadata}
\pgfmathresult
\pgfkeys{/pgf/fpu=false}
}`

Grazie
