It displays numbers in user configurable fixed, scientific, or engineering formats. The user configurable calculator has sixteen user configurable function buttons that can each be assigned two functions from 75 built-in functions and access an unlimited number of user defined macro functions. It displays numbers in user configurable fixed, scientific, or engineering formats. The programmer’s calculator has a hexadecimal keypad and displays numbers in user configurable hexadecimal format.
