QmuTokenParser class constructor. Make easy initialization math parser.
This constructor hide initialization variables, operators, character sets. Use this constuctor to get tokens from formula. All formulas must be converted to external look. Example:
QmuTokenParser *cal = new QmuTokenParser(formula, osSeparator, false); tokens = cal->GetTokens(); numbers = cal->GetNumbers(); delete cal;
| formula | string with formula. |
| fromUser | true if we parse formula from user |
