我有这个代码:

#include <iostream>
#include <cmath>
#include <stdlib.h>
using namespace std;
double f(double x);
double biseccion(double a, double b, double tolerancia, int maxiter);
int main()
{
    double a, b, raiz;
    double tolerancia=0.00000;
    int maxiter=25;
    cout << "Input begin of interval: ";
    cin >> a;
    cout << "Input end of interval: ";
    cin >> b;
    cout << "\n";
    cout << "  # de"<<"\n"<<"Iteration"<<"\t"<<"   A"<<"\t"<<"   B"<<"\t"<<"   C"<<"\t"<<"   f(c)"<<endl;
    raiz=biseccion(a,b,tolerancia,maxiter);
    cout << "\n";
    cout << "The root is: "<< raiz <<endl;
    return 0;
} …

嗨,我正在用MIPS编写一个小程序,在9之间除以2并显示结果.这是代码

li $t1, 2
li $t2, 9
li $v0, 2
div $t0,$t2,$t1
move $a0,$t0
syscall

(这不是完整的代码,只是部门处理部门)

所以,2/9是0.2222222222222222

但是当我运行它时我只得到0.0

我如何显示真实结果(0.2222222222222222)？

我曾经说过我使用的是整数而不是浮点数,我必须使用浮点指令来获得十进制结果.我应该查看div.x指令,但div.x不是一个可识别的运算符.

所以,我几乎是空白.我不明白该怎么做.

有人可以发布代码来显示浮点结果吗？

提前致谢.

我试图向自己解释以下8085汇编代码

我有这个代码要求两个数字(来自IDE中的虚拟键盘)并在LED 7和8上显示它们:

我正在尝试使用CodeIgniter和NetBeans在PHP中进行小型项目.我有这个HTML视图:

<div class="section section_with_padding" id="users">
