1. Is this a positive or a negative number?
0010 0000 is the binary representation of a positive integer, on 8 bits.
In a signed binary, the first bit (the leftmost) is reserved for the sign,
1 = negative, 0 = positive. This bit does not count when calculating the absolute value.
2. Construct the unsigned binary number.
Exclude the first bit (the leftmost), that is reserved for the sign:
0010 0000 = 010 0000
3. Map the unsigned binary number's digits versus the corresponding powers of 2 that their place value represent:
26
0 25
1 24
0 23
0 22
0 21
0 20
0
The number 0010 0000(2) converted from a signed binary (base two) and written as an integer in decimal system (base ten):
0010 0000(2) = 32(10)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
