DSP code – when to use floats or when to use doubles (in: DSP and Plugin Devel…)

The flaw is that DSP are math formulas.The math calculation results need not to be in the dynamic range of human hearing.
Example: a formula that has powers of e.g. 20 both in the numerator and denominator. The result could be in the audio dynamic range if the magnitudes cancel out, but the intermediate variables for the computation need not to be.
Some algorithms are subject to precision issues, others aren’t.
