But of course, the Basic interpreters on the 8-bit machines, having to implement floating point in software anyway, on CPUs that did things 8 or at most 16 bits at a time, were not obliged to stick to such power of 2 formats.

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. WebApr 21, 2015 · The explanation for this can be that floating point formats are intended for intermediate use in production setups due to very little loss of dynamic range, where future processing (gain-staging, compressing, limiting etc.) can bring back the values (without loss) well within the final and normal -0.2 - 0 dB range; and therefor preserves the …
