I heard about a friend of mine complaining he couldn&#x27;t get the right percentage value out of his phone&#x27;s calculator, while working in a patisserie.<p>He doesn&#x27;t get how to compute percentages.<p>Thus I coded a little (nice?) one, targeted for his phone with very low resolution&#x2F;crappy display.<p>Maybe someone might find it useful (though I don&#x27;t think so, really)
