- epicardium/rtc: fix numerically unstable subsecond decoding · 756c13df
  Ferdinand Bachmann authored 5 years ago
  
  the subsecond encoding function from epic_rtc_set_milliseconds and the corresponding decoding function from epic_rtc_get_milliseconds are not numerically stable. i.e., encoding 5 milliseconds to 20 subsecs and immediately afterwards decoding that yields 4 milliseconds. Adding a bias of 999 (0.24 milliseconds) to the decoding function makes it numerically stable, while never decoding any subsecond value to more than 999 milliseconds.
