Generally, for custom formatting, it's easiest to use:

void
gtk_tree_view_column_set_cell_data_func (GtkTreeViewColumn   *tree_column,
                                         GtkCellRenderer     *cell_renderer,
                                         GtkTreeCellDataFunc  func,
                                         gpointer             func_data,
                                         GtkDestroyNotify     destroy)

With this function, you can retrieve the values from your model,
format them with g_strdup_printf() and set them on the renderer
itself.

You could also just have another column in the model with the number
preformatted as a string.
