How to use the yaml-ast-parser.parseYamlFloat function in yaml-ast-parser

const result = new NumberASTNode(
            parent,
            instance.startPosition,
            instance.endPosition,
          );
          result.value = Yaml.parseYamlInteger(value);
          result.isInteger = true;
          return result;
        }
        case Yaml.ScalarType.float: {
          const result = new NumberASTNode(
            parent,
            instance.startPosition,
            instance.endPosition,
          );
          result.value = Yaml.parseYamlFloat(value);
          result.isInteger = false;
          return result;
        }
        case Yaml.ScalarType.string: {
          const result = new StringASTNode(
            parent,
            false,
            instance.startPosition,
            instance.endPosition,
          );
          result.value = instance.value;
          return result;
        }
      }
      break;
    }
