How can Java convert a string of numbers into currency
Publish: 2021-04-21 17:25:52
1.
-
the cursor is in front of the number and the point is inserted
-
select the currency symbol, such as & #;, Then click the insert button
-
just add. 00 after the number
2. Ore (part of the world is nihilistic)

如果表达小于2^31-1的正数代码如下：
public void binaryToDecimal(int n){
int t = 0; //用来记录位数
int bin = 0; //用来记录最后的二进制数
int r = 0; //用来存储余数
while(n != 0){
r = n % 2;
n = n / 2;
bin += r * Math().pow(10,t);
t++;
}
System.out.println(bin);
}
使用字符串的拼接+来实现大于2^31-1的数，代码如下:
public void binaryToDecimal(int n){
String str = "";
while(n!=0){
str = n%2+str;
n = n/2;
}
System.out.println(str);
}
可以右移后再与0x01进行&运算得到第一位的数字判断判断它的第几位上是0，第几位上是1，代码如下：
class ByteMove
{
public static void main(String[] args)
{
int i = 7;
move(i);
}
static void move(int num){
for(int i= 0;i<6;i++){
System.out.println("第"+(i+1)+"位：" + (num >> i & 0x01));
}
}
}
