十六進制中, 每兩個為一個byte, 如4字節表示`00 00 00 FF`

十進制到其他進制
```javascript
let a = 54463

a.toString(16) // 十到十六
a.toString(10) 
a.toString(8) // 十到八
a.toString(2) // 十到二

'd4bf'
'54463'
'152277'
'1101010010111111'
```


其他進制到十進制

```javascript
let x = 110

parseInt(x, 2)
parseInt(x, 8)
parseInt(x, 16)


6
72
272
```

其他轉其他

先用`parseInt`轉為十進制, 再用`toString`轉為其他進制
                    
                
        
                
            
        
                
    
                
    
                
        
                
    
                

                







                  <ruby id="bdb3f"></ruby>
                  <p id="bdb3f"><cite id="bdb3f"></cite></p>
