I posted this before: http://www.sparetimelabs.com/densitometer/densitometer.php That is a story of a densitometer (film optical density measurement device) that was implemented in an 8 bit (68HC11) assembler using 24 bit floating point, hand crafted in assembly. So I think this should qualify as something 'very close in spirit'. The source code is there too in case someone is interested. Even though I had to write the FP myself I thought at the time that using FB was the easies way to implement this. This device measures the amount of light passing through a strip of movie film to access the quality of the film development process, which is calculated at log10 of (I0/I) where I is the amount of light passing through the film under test and I0 is the same measurement without the film in the measurement chain. The range of I0/i is ~ 1-10000 for film densities of 0.01 to 4.00 and we required three digits of precision so I figured that FP was the easiest way to go. I may have been wrong there (it being the easiest) but it worked for me. br Kusti This e-mail may contain confidential or privileged information.
