|
|
* @brief The Calculator class for calculation formula.
|
|
*
|
|
* Main purpose make easy evaluate value of formula and get tokens.
|
|
* Note. If created to many parser for different purpes in the same time parser can work wrong.
|
|
* Example:
|
|
* DialogEditWrongFormula *dialog = new DialogEditWrongFormula(data);
|
|
* dialog->SetFormula(formula);
|
|
* if (dialog->exec() == QDialog::Accepted)
|
|
* {
|
|
* formula = dialog->GetFormula();
|
|
* //Need delete dialog here because parser in dialog don't allow use correct separator for parsing here.
|
|
* //Don't know why.
|
|
* delete dialog;
|
|
* Calculator *cal = new Calculator(data);
|
|
* result = cal->EvalFormula(formula);
|
|
* delete cal;//Here can be memory leak, but dialog already check this formula and probability very low.
|
|
* }
