We need signed integers in order to represent both negative and positive values. However, some numbers can never be negative. For instance, the size of a file must always be greater than or equal to zero so we use unsigned integers to represent file sizes. Also, natural numbers must be greater than 0 so there's no point in using a signed value to represent a natural number. Signed integers also use one bit to denote the sign, but unsigned integers do not thus unsigned integers can effectively represent twice the range of positive values than an unsigned integer can. For instance, an 8-bit signed value can represent values in the range -128 to +127 using twos complement notation, but an 8-bit signed value can represent values in the range 0 to 255.
What is the significance of declaring a constant unsigned integer?
One of them is signed, the other is unsigned.
signed integer means that it has a sigh (+ or -). Using another words you say that signed variable can be positive as well as negative. unsigned variables can be only positive.
Having an unsigned integer means that the integer is positive, and not negative; literally, the integer is unsigned and assumed to be positive. The unsigned integer 8 is positive-eight, not negative-eight.
The highest unsigned integer is 255; The highest signed integer is 127.
An unsigned integer cannot be negative. It has a maximum positive value twice that of a signed integer. Max signed: 128 Max signed: 256 I could be off by one there, though.
Signed integer is any integer that carries negative sign while unsigned integer is any integer that carries positive sign
A signed integer is one with either a plus or minus sign in front. That is it can be either positive or negative.An unsigned integer is assumed to be positive
a signed number is one that can be negative (have a sign) whereas an unsigned number will only be positive. due to less information, you can double the largest number storable in a signed integer to get the data available in an unsigned integer. However, PHP doesn't have unsigned integers, they're all signed.

Integer (signed or unsigned)
No..Java Supports Signed positive and negative integers

if it is a signed int the the range is -32768 to 32767if its unsigned then 0 to 65535
