If your 4th Dimension database uses decimal numbers, you probably store and manipulate those numbers in fields and variables of type Real. This technical note examines the characteristics and behaviors of Reals in 4D, and touches on the following issues:

• NAN’s: When is a number not a number?
• Using 4D Customizer to change the way real numbers display
• Comparing real numbers
