用于将整数转换为罗马数字的JavaScript算法
假设，我们需要编写一个函数sayintToRoman()，顾名思义，该函数返回罗马数字，该数字等于传入的数字作为参数。
让我们为该函数编写代码-
示例
const intToRoman = (num) => {
let result = "";
while(num){
if(num>=1000){
result += "M";
num -= 1000;
}else if(num>=500){
if(num>=900){
result += "CM";
num -= 900;
}else{
result += "D";
num -= 500;
}
}else if(num>=100){
if(num>=400){
result += "CD";
num -= 400;
}else{
result += "C";
num -= 100;
}
}else if(num>=50){
if(num>=90){
result += "XC";
num -= 90;
}else{
result += "L";
num -= 50;
}
}else if(num>=10){
if(num>=40){
result += "XL";
num -= 40;
}else{
result += "X";
num -= 10;
}
}else if(num>=5){
if(num>=9){
result += "IX";
num -= 9;
}else{
result += "V";
num -= 5;
}
}else{
if(num>=4){
result += "IV";
num -= 4;
}else{
result += "I";
num -= 1;
}
}
}
return result;
};
console.log(intToRoman(178));
console.log(intToRoman(89));
console.log(intToRoman(55));
console.log(intToRoman(1555));输出结果
控制台中此代码的输出为-
