Big Endian & small Endian
0x12345678:
Small Endian: 0x78 0x56 0x34 0x12
Big Endian: 0x12 0x34 0x56 0x78
以下為範例程式(BigEndian_to_SmallEndian)
function BigEndian_to_SmallEndian(hexNum) {
let SmallEndian_array = [];
if (hexNum.length % 2 !== 0) {
hexNum = '0' + hexNum // 數字總數為奇數的話 在開頭補0
}
for (let i = 0, len = hexNum.length; i < len; i++) {
if (i % 2 !== 0) {
SmallEndian_array.unshift(hexNum.charAt(i - 1) + hexNum.charAt(i))
}
}
return SmallEndian_array.join('');
}
如果要把Smail 轉為BIg Endian則為同一個程式,把數字再放入跑一次即可轉回
