Decimal 9866 = 10011010001010 Binary


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

Here’s the proof that 10011010001010 is the correct result:

1×2^13 + 0x2^12 + 0x2^11 + 1×2^10 + 1×2^9 + 0x2^8 + 1×2^7 + 0x2^6 + 0x2^5 + 0x2^4 + 1×2^3 + 0x2^2 + 1×2^1 + 0x2^0 = 9866

Now you already know the most important thing:

1001101000101010 equals 98662 if unsigned.

If 9866 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00010011010001010 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 9866 signed using two’s complement, will start with one or more 1’s, but the exact code for -9866 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
