为何用负基？怎么读？Why a negative base? How do I read it?

基为 −10 时，从右往左第 k 位（从 0 起）的权重是 (−10)^k，所以不需要负号就能表示所有整数。例如 190 = 1×100 + 9×(−10) + 0 = 10，而 −10 写成 10。With base −10, the k-th digit from the right (counting from 0) has weight (−10)^k, so every integer can be written without a minus sign. For example 190 = 1×100 + 9×(−10) + 0 = 10, while −10 is written 10.
