An N-bit integer holds 2N different values.For an unsigned integer, the range of values is 0..2N-1 thus.For a signed integer using 2s complement, the range is -2N-1..+2N-1-1.Therefore, the largest positive number that can be stored using 8 bits is 255.
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
In number Systems , there are integer numbers whose range lies from negative to positive numbers. negative four number as an integer can be written as -4.With a sign of minus infront of it.
For an unsigned integer, that would be 216-1. For a signed integer in 2's complement notation, the largest number would be 215-1.
No, it is an integer.
