40001₁₀ = 1001110001000001₂
Decimal 40001 = 1001110001000001 Binary

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

Here’s the proof that 1001110001000001 is the correct result:

1×2^15 + 0x2^14 + 0x2^13 + 1×2^12 + 1×2^11 + 1×2^10 + 0x2^9 + 0x2^8 + 0x2^7 + 1×2^6 + 0x2^5 + 0x2^4 + 0x2^3 + 0x2^2 + 0x2^1 + 0x2^0 = 40001

Convert 40001 to Binary

Now you already know the most important thing:

1001110001000001₁₀ equals 40001₂ if unsigned.

If 40001 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 0001001110001000001 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 40001 signed using two’s complement, will start with one or more 1’s, but the exact code for -40001 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
