javascript int對二進制但打印是無限的

Question

data = parseInt(num); 
    bin =0; 
    pow=1; 
    var rem=0 ; 
while(data != 0){ 
    rem = data % 2; 
data = data/2; 
    bin = rem * pow + bin; 
    pow = pow *10; 
    } 

    document.write(bin); 

例如53是110110.但打印在JavaScript中是無窮大。我的錯在哪裏？

Answer 1

你可以做到以下幾點：

parseInt('53').toString(2); // returns 110110 

或只是

(53).toString(2); 

全：

var num = prompt("Please enter an integer between 0 and 255", ""); 

document.write(parseInt(num, 10).toString(2));
