QString Minicli::calculate(const QString &exp)
{
   QString result;
   QString cmd;
//<<
   if( !KStandardDirs::findExe( "bc" ).isEmpty()) {
      QString expWithPoints = exp.replace(",", ".");
      cmd = QString("echo \"scale=20;%1\" | bc" ).arg(expWithPoints);
   } else
//>>
      cmd = QString("echo $((%1))").arg(exp);
   FILE *fs = popen(QFile::encodeName(cmd).data(), "r");
   if (fs)
   {
      QTextStream ts(fs, IO_ReadOnly);
      result = ts.read().stripWhiteSpace();
      pclose(fs);
   }
   return result;
}

No ?
A problem with that ?
I search... but I find it trivial.
But I'm not an expert hacker :-)
