C++实现数字转换为十六进制字符串的方法

function toHex(number, min){  var hexes = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'];  var hex = '';  var min = min || 2;  var nibble;  do  {    nibble = number & 0x0f;    number = number >> 4;    hex = hexes[nibble] + hex;  }  while( number );  if( hex.length < min )  {    hex = new Array(min-hex.length+1).join('0') + hex;  }  return '0x'+hex;}
