1. Is this a positive or a negative number?
0000 0000 0000 1110 1101 0011 1010 1110 is the binary representation of a positive integer, on 32 bits (4 Bytes).
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:
0000 0000 0000 1110 1101 0011 1010 1110 = 000 0000 0000 1110 1101 0011 1010 1110
3. Map the unsigned binary number's digits versus the corresponding powers of 2 that their place value represent:
230
0 229
0 228
0 227
0 226
0 225
0 224
0 223
0 222

4. Multiply each bit by its corresponding power of 2 and add all the terms up.
000 0000 0000 1110 1101 0011 1010 1110(2) =
(0 × 230 + 0 × 229 + 0 × 228 + 0 × 227 + 0 × 226 + 0 × 225 + 0 × 224 + 0 × 223 + 0 × 222 + 0 × 221 + 0 × 220 + 1 × 219 + 1 × 218 + 1 × 217 + 0 × 216 + 1 × 215 + 1 × 214 + 0 × 213 + 1 × 212 + 0 × 211 + 0 × 210 + 1 × 29 + 1 × 28 + 1 × 27 + 0 × 26 + 1 × 25 + 0 × 24 + 1 × 23 + 1 × 22 + 1 × 21 + 0 × 20)(10) =
(0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 524 288 + 262 144 + 131 072 + 0 + 32 768 + 16 384 + 0 + 4 096 + 0 + 0 + 512 + 256 + 128 + 0 + 32 + 0 + 8 + 4 + 2 + 0)(10) =
(524 288 + 262 144 + 131 072 + 32 768 + 16 384 + 4 096 + 512 + 256 + 128 + 32 + 8 + 4 + 2)(10) =
971 694(10)
5. If needed, adjust the sign of the integer number by the first digit (leftmost) of the signed binary:
0000 0000 0000 1110 1101 0011 1010 1110(2) = 971 694(10)
The number 0000 0000 0000 1110 1101 0011 1010 1110(2) converted from a signed binary (base two) and written as an integer in decimal system (base ten):
0000 0000 0000 1110 1101 0011 1010 1110(2) = 971 694(10)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
