True. But in the link you mentioned 4 digits of precision. Would you have fitted this into 16-bit floats? Ran all the calculations including log on 11 bits prec? Anyone using 16 bit floats in a real embedded app now? Just curious whether there is actual "customer demand" pushing for this... Every time I think of soft floats on 8 bit MCUs, they always end up sounding better as 24-bit float formats... IIRC even 6502 Microsoft BASIC floats were formatted for easier byte-sized handling. Is there no way of using 16 bit floats easily without packing and unpacking? -- Cheers, Kein-Hong Man (esq.)
