Java语言中JS toFixed(2)方法的同义词是什么? 只有选项是DecimalFormat?
答案 0 :(得分:0)
没有,但你可以这样做:
/**
* Shortens a float to a specified length
* @param num The float to shorten
* @param to The length
* @return the shortened version
**/
public static String toFixed(float num, int to){
//Split at the decimal point
String[] s = String.valueOf(num).split("[.]");
//Combine the two so and shorten the second
String ending = s[1].substring(0, ((s[1].length() > to) ? to : s[1].length()));
return s[0] + '.' + ending;
}
虽然这不是圆的
