Convert decimal number 62 to binary number Yes

(62) 10
= (0*1010 + 110) * 1010 + 10) 2
= (110*1010 + 10) 2
= (111100 + 10) 2
= (0, 111110) 2

Javascript 10-to-16-to-zero

Because js does not have a method similar to '0' * x, and there is no function similar to using a character string that is less than the specified length, you can only write
Function str_pad (hex ){
Var zero = '20140901 ';
Var tmp = 8-hex.length;
Return zero. substr (0, tmp) + hex;
}
