EXAMPLE - Rounding Functions
The following example demonstrates how the rounding functions work together. These functions include the following:
FLOOR- largest integer that is not greater than the input value. See FLOOR Function.CEILING- smallest integer that is not less than the input value. See CEILING Function.ROUND- nearest integer to the input value. See ROUND Function.MOD- remainder integer when input1 is divided by input2. See Numeric Operators.
