Decimal 218 = 11011010 Binary


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

Here’s the proof that 11011010 is the correct result:

1×2^7 + 1×2^6 + 0x2^5 + 1×2^4 + 1×2^3 + 0x2^2 + 1×2^1 + 0x2^0 = 218

Now you already know the most important thing:

1101101010 equals 2182 if unsigned.

If 218 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00011011010 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 218 signed using two’s complement, will start with one or more 1’s, but the exact code for -218 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
