Floating point calculations in HCS12 - Patrick - Apr 24 22:20:55 2008
Hi there, I'm struggling to figure out how to multiply by floats in the
HCS12. For example, let's say we wanted to multiply 100 by 0.165. My
initial idea was to multiply 100 by 165 and then divide that result by
1000. I did this using the emul and ediv instructions, however I am
not getting correct results in my implementation. Could anyone provide
an example of how to do this? Thanks!
