  1. Fixed-point number representation C2 formal

    A method of representing real numbers in computing where the radix point (decimal point) is fixed at a specific position, allowing for a limited range but precise fractional values.

    • Fixed-point notation is often used in embedded systems for efficient arithmetic.
    • The programmer chose fixed-point notation over floating-point for better performance.
    • In fixed-point notation, the number 12.34 might be stored as 1234 with an implied decimal point.
