Java中的絕對(duì)值函數(shù)是Math.abs()
,它在以下幾種情況下非常有用:
int a = -5;
int b = 3;
int distance = Math.abs(a - b); // distance will be 8
int number = -10;
int filteredNumber = Math.abs(number); // filteredNumber will be 10
int index = -7;
int validIndex = Math.abs(index); // validIndex will be 7
int x = -3;
int y = 4;
int distance = Math.sqrt(x * x + y * y); // distance will be 5
int angle = Math.atan2(y, x) * 180 / Math.PI; // angle will be in degrees
總之,Java中的絕對(duì)值函數(shù)Math.abs()
在許多場(chǎng)景中都有廣泛的應(yīng)用,可以幫助我們處理各種數(shù)值計(jì)算和邊界檢測(cè)問題。
