基数幂
cardinal power
- 对于小的整数幂，比如2和3(或以2为基数，这比较特殊)，通常会选择完全错误的算法。
It usually chooses completely the wrong algorithm for small integral powers like two and three, or for special cases like a base of two. - 十进制系统的基数为10，且从小数点每左进一位或者右退一位，其权增加或者减少10的幂次。
In the decimal system the base or radix is 10, and each position to the left or right of decimal point presents an increased or decreased weight as power of 10. - 二进制系统的基数为2，且从小数点每左进一位或者右退一位，其权增加或者减少2幂次。
In binary system the radix is 2, and the positions to the left or right of the binary point carry weight increasing or decreasing in power of 2.
