Convert "Little-Endian" to "Big-Endian"

Convert "Little-Endian" to "Big-Endian"

This tip outlines two simple methods that help you to convert a number from the "little-endian" format to the "big-endian" format.

// 2-byte number
int SHORT_little_endian_TO_big_endian(int i)
{
    return ((i>>8)&0xff)+((i << 8)&0xff00);
}

// 4-byte number
int INT_little_endian_TO_big_endian(int i)
{
    return((i&0xff)<<24)+((i&0xff00)<<8)+((i&0xff0000)>>8)+((i>>24)&0xff);
}
