[QUOTE="robbor, post: 157052, member: 1420"] Im building a cosine angle indicator and am wondering how many significant digits I should use for long range. I notice that the ACI only uses 2 digits and I just captured a pic from the back of a Suunto angle indicator and they use 4 digits. Any body play with more than 2 digits for long range? 5degrees off of level: ACI .99 Suunto .9962 15 .96 .9659 25 .91 .9063 Looks like they only differ by about 4 yards or so out to 1000. [/QUOTE]
