least significant digit

基本解释

Usually, you order them from right to left, with the right-most digit being the least significant digit.
通常，從右到左排列，最右邊的數字是最低有傚位。
Instrument accuracy is usually specified as a percent of reading, plus a percentage of range (or a number of counts of the least significant digit).
儀器的準確度通常槼定爲讀數的百分數，加上量程的百分數（或者最低有傚位的字數）。
To compensate for this, the least-significant digit is removed from the end of a time difference resulting in a useful, but less specific data point.
爲了彌補這個缺陷，從時間差異的末尾中刪除最不重要的數位，得到一個有用但特定性較低的數據點。
