851₁₀ = 1101010011₂
Decimal 851 = 1101010011 Binary

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

Here’s the proof that 1101010011 is the correct result:

1×2^9 + 1×2^8 + 0x2^7 + 1×2^6 + 0x2^5 + 1×2^4 + 0x2^3 + 0x2^2 + 1×2^1 + 1×2^0 = 851

Convert 851 to Binary

Now you already know the most important thing:

1101010011₁₀ equals 851₂ if unsigned.

If 851 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 0001101010011 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 851 signed using two’s complement, will start with one or more 1’s, but the exact code for -851 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
