今天运行一个程序,发现一个很有意思的情况,可以看到代码如下所示 public static void main(String[] args) {float a = 1;for (int i = 0; i<20000000; i++) {a++;}System.out.println(a); }public static void main(String[] args) {float a = 20000000;float b = a + 1;float c = b - a;System.out.p

之前在进行蓝桥杯赛题训练的时候,有一题涉及到实数,提交以后有一个案例通过不了,检查一看发现是数据精度丢失了,导致最终的结果出错,现记录如下. 首先,让我们来测试一下 测试代码: import java.util.Scanner; public class test {public static void main(String[] args) {// TODO Auto-generated method stubScanner sca=new Scanner(System.in);while(t
问题 身边有同学要投今年的ICASSP,但对能不能提交supplementary information并不确定.原因是ICASSP官网上说的是: LENGTH: You are allowed a total of 5 pages for your document. Up to 4 pages may contain technical content, figures, and references, while the 5th page may contain only referenc
