20910 = 110100012
Decimal 209 = 11010001 Binary


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

Here’s the proof that 11010001 is the correct result:

1×2^7 + 1×2^6 + 0x2^5 + 1×2^4 + 0x2^3 + 0x2^2 + 0x2^1 + 1×2^0 = 209

Now you already know the most important thing:

1101000110 equals 2092 if unsigned.

If 209 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00011010001 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 209 signed using two’s complement, will start with one or more 1’s, but the exact code for -209 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
