Fixed point and floating point numbers
WebA floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 31 − 1 = 2,147,483,647, whereas an IEEE 754 32-bit base-2 floating-point variable has a maximum value of (2 − 2 −23) × 2 127 ≈ 3.4028235 ... WebMay 29, 2024 · Floating-point offers dynamic range, meaning it can handle large or small numbers by varying the exponent as part of calculations. Fixed-point has only static range—it can represent large numbers or small numbers, but you have to choose the range when designing the code.

Webnumbers—for fixed-point devices. Overall, fixed-point DSPs still have an edge in cost and floating-point DSPs in ease of use, but the edge has narrowed until these factors should no longer be overriding in the design decision.
