13. 15. 1. The ROUND Function

ROUND is very similar to the TRUNC function.

It uses the same format mask as TRUNC.

ROUND rounds up or down based upon the format mask.

The default mask when specifying a DATE value is DD.

Some useful purposes for this are

Rounding to the nearest minute for billing cellular-based calls
Rounding to closest month to determine a pay period

The Syntax for the ROUND Function
