The difference in comfort isn’t worth the price difference.(my opinion) There’s less to go wrong in a 2 stage vs modulating so it’s more reliable. Certain components are cheaper to replace in the 2 stage.

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". WebApr 23, 2024 · Floating-point arithmetic can exhibit inconsistent behavior related to things like global rounding modes, optimisation, associativity, implementation-defined behavior, and variations in FPU hardware.
