Web2 Answers Sorted by: 2 So basically, "float" means that it stores a significand and a base exponent. A "standard" 32-bit float uses 1 bit for sign, 8 bits for exponent and 23 bits for signifcand. The key here is that the scale (the exponent) is stored with the number. "Fixed" is stored hi-word/low-word "packed". WebAug 4, 2024 · The key point of the modulating control is continuous control action. The example is when the sensor of the modulating system senses a deviation from the set-point, the thermostat/controller will calculate the amount of the error to determine what signal should be sent to the actuator.
