倒数![]() ![]() ![]() 数学上,一个数 汉语中,名词倒数一般用来表示数字的乘法逆,一般在各种数域如:有理数、实数、复数,以及模n的同余类所构成的乘法群中使用。在复数域(实数域)中,每个除了0以外的复数(实数)都存在倒数:只要用某个数自身除1(也就是说用1除以某个数),即可得到它的倒数。用数学记号表示的话:
英语百科
Multiplicative inverse 倒数![]() ![]() ![]() In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4. The reciprocal function, the function f(x) that maps x to 1/x, is one of the simplest examples of a function which is its own inverse (an involution).
