Does anyone know of a way to round to thousands in excel with a custom
format. I am trying to round as follows:

If the number is 49,677,298.86 I want 49,600 to display
If the number is 3,037,136.67 I want 3,000 to display
If hte number is 2,369,098.33 I want 2,400 to display

Thanks for your help.
