欧氏距离 [英] euclidean distance

问题描述

我正在做一个关于两个一维信号之间的欧几里德距离的任务

如果输入为2个整数数组的形式，则平方根输出应为整数，因为平方根输出为float或double
谢谢

I''m doing a task about euclidean distance between two 1d signals

if the input is in the form of 2 arrays of integers should the output after square rooting be integer since square root outputs float or double
thanks

推荐答案

整数的平方根显然可以是浮点数，实际上，它的确经常会是浮点数.

The square root of an integer can obviously be a floating point number, and, in fact, will be, more often than not.
