hi all,

i've got a question about the PD_BADFLOAT macro ...

iirc denorms occur when there a number is below 2^(-127), what's about 5.9e-39, what's definitely inaudible ... if sound files are stored as 24 bit pcm, pd's representation of samples as floats between -1 and 1 would result a max. resolution of 4.7e-10 ...

which floats will be marked by pd's macro? only floats that are actually denormals? or all samples that are below a certain threshold? if it's only detecting actual denormals what do you think of adding some kind of PD_NEARLYBADFLOAT macro that flushes every float below maybe 1e-20 to zero ... then we can be more or less sure, that no future function (e.g. fftw) will actually create denormal values ...

cheers...
