signed means the data can contain a - (negative) sign.
ex.
| signed int = -1024 through 1024 |
| unsigned int = 0 through 2048 |
Unsigned is essential in working with bit's because you can use the whole data field instead of half. Other than that, the choice is up to you.
-"What we wish, we readily believe, and what we ourselves think, we imagine others think also."PHP Code:sadf
signed uses the highest binary bit to identify the sign
