About Fixed-Point Numbers

Fixed-point numbers represent fractional values using integer arithmetic by allocating a fixed number of bits to the fractional part. For example, with 8 integer bits and 8 fractional bits:

• The value 3.25 is stored as 832 (3 × 256 + 0.25 × 256)
• In binary: 00000011.01000000
• In hex: 0x0340

This representation is commonly used in embedded systems, digital signal processing, and situations where floating-point arithmetic is unavailable or too expensive.
