Signed and Unsigned Arithmetic Operations using java The XDR standard defines signed integers as integer . A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a nonnegative integer in the range [0 to 4294967295]. The signed integer is represented in twos complement notation. The most significant byte is 0 and the least significant is 3. The unsigned integer is represented by an unsigned binary number whose most significant byte is 0; the least significant is 3. See the Signed Integer and Unsigned Integer. The XDR standard also defines 64-bit (8-byte) numbers called signed and unsigned hyperinteger . Their representations are extensions of signed integers and unsigned integers. Hyperintegers are represented in twos-complement notation. The most significant byte is 0 and the least significant is 7. See the Signed Hyperinteger and Unsigned Hyperinteger figure. The ...
