What’s the Difference Between Fixed-Point, Floating-Point, and Numerical Formats? #embedded https://t.co/2hcw10KVVV

Download this article in PDF format. Embedded C and C++ programmers are familiar with signed and unsigned integers and floating-point values of various sizes, but a number of numerical formats can be used in embedded applications. Here we take a look at all of these formats and where they might be found. One reason for examining different formats is to understand how they work and where they can be applied. For example, fixed-point values can often be used when floating-point support isn’t available. Fixed point may be preferable in some instances, while floating-point support is available for other reasons, such as precision or representation. Developers may be using single- and double-precision IEEE 754 standard formats, but what about 16-bit half precision or even 8-bit floating point? The latter is being used in deep neural networks (DNNs), where small values are usefu...
