Similar to currency ($) default formats, the list of percentage (%) default formats have one or two decimal points.
Sometimes that is fine, but many times it's best to have the percentage value as a whole number (without any decimals) as its easier to evaluate more complex data, particularly when visually presented on a Databoard.
For example, 89.63% is usually better displayed as simply 90%.
Currently, we have to create Custom Formats to display percentage values as whole numbers (without any decimals) (the same as with currency values).
The whole number Format options should be included on the drop-down list of Default Formats.
