missing comma in "dec" function

[paquinmathieu]

this line is missing in the second if

     res += '.';

        if ( ! flo && diff ) {
          res += '.';
          for ( let i = 0; i < diff; i++ ) {
            res += '0';
          }
        }

        if ( flo && diff > 0 ) {
          for ( let i = 0; i < diff; i++ ) {
            res += '0';
          }
        }

should be change to

        if ( ! flo && diff ) {
          res += '.';
          for ( let i = 0; i < diff; i++ ) {
            res += '0';
          }
        }

        if ( flo && diff > 0 ) {
          res += '.';
          for ( let i = 0; i < diff; i++ ) {
            res += '0';
          }
        }
