20965₁₀ = 101000111100101₂
Decimal 20965 = 101000111100101 Binary

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

Here’s the proof that 101000111100101 is the correct result:

1×2^14 + 0x2^13 + 1×2^12 + 0x2^11 + 0x2^10 + 0x2^9 + 1×2^8 + 1×2^7 + 1×2^6 + 1×2^5 + 0x2^4 + 0x2^3 + 1×2^2 + 0x2^1 + 1×2^0 = 20965

Convert 20965 to Binary

Now you already know the most important thing:

101000111100101₁₀ equals 20965₂ if unsigned.

If 20965 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000101000111100101 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 20965 signed using two’s complement, will start with one or more 1’s, but the exact code for -20965 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
