## Common Functions

Functions are modifiers used to manipulate the data. These are predefined by the software itself, and must be used to perform specific functions.

IsNull(): This is used to determine if the value of an object is null. It will return true if the value is null, or False if the object contains data

Sum(): Sums numeric data in a formula

If/Then/Else(): This combination of functions is used together to compare different objects and/or values to one another, using true/false logic

Count(): Provides a distinct count of objects in a table

Min/Max(): Returns the minimum (min) or maximum (max) value of objects in a table

• If the data is numeric, this will return the lowest number
• If the data is text, if will return the first value alphabetically
• If the data is dates, it will return the earliest date
