Hi Martin and thanks for your lib.
I was trying to use a 2nd Order LP filter and was always given 0 as output of filterIn() call.
I think that is because I have values for all coefficients k0, k1, k2 smaller than FLT_EPSILON (i.e. EPSILON=1e-5 in your code). I also noticed that there is no way for these coefficients to ever get bigger than EPSILON for any sensible choice of ts and hz (i.e. considering Shannon Theorem, Hz > 2/ts): see image below.
Am I missing something here?
