Formatting Cell Values

123456.789 => 0.#### => 123456.789
123456.789 => 0,000.#### => 123,456.789
123456.7891 => 00,00.#### => 12,34,56.7891
123456 => 0.#### => 123456

mygrid.setNumberFormat(“0,000.####”,index,".",",");

I would like to have the same result as above.
What should I do? help me.

Unfortunately your requirements are not very clear.
Couldn’t you explain it in the other words or using screenshots.
