Simple text-to-numbers library wriiten in java. Based on https://github.com/Doomer3D/Genesis.CV

You can tune the tokenMaxError option to get optimal results

  var parsed =
               RussianNumber.parse("ваше число",  new RussianNumberParserOptions().setMaxTokenError(0.3));

maxTokenError = 0.3 is optimal if you have a some trash input like a "Думаю девать", with this value library skip "Думаю" and trying to parse "девять" you can set any value from 0.0 to 1.0 and find best value for your task

To convert from text to digit value try to run this code

       import RussianNumber;
       // some code
       string text = "сто двадцать три"
       var parsed = RussianNumber.parse(value.Text);

To convert from number to text value try to run this example

        import RussianNumber;
        // some code
        long value = 123;
        var parsed = RussianNumber.getStringValue(value);
