While computers, CPUs, and electronic devices store numbers in binary format, most often they represent real numbers as floating point numbers, or floats. For example, in industrial automation applications, all analog values read from an I/O unit are floats.

This document describes how the IEEE 754 standard for floats is used in Opto 22 products, including groov RIO, groov EPIC, and SNAP PAC systems.
