Decimal 27 = 11011 Binary


Any integer can be written as sum of potencies to the power of 2, known as binary code.

Here’s the proof that 11011 is the correct result:

1×2^4 + 1×2^3 + 0x2^2 + 1×2^1 + 1×2^0 = 27

Now you already know the most important thing:

1101110 equals 272 if unsigned.

If 27 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00011011 in which the leftmost bit is the sign bit, followed perhaps by more trailing 0’s, and then by magnitude bits.

The reason to have the binary signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 27 signed using two’s complement, will start with one or more 1’s, but the exact code for -27 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
