2421₁₀ = 100101110101₂
Decimal 2421 = 100101110101 Binary

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

Here’s the proof that 100101110101 is the correct result:

1×2^11 + 0x2^10 + 0x2^9 + 1×2^8 + 0x2^7 + 1×2^6 + 1×2^5 + 1×2^4 + 0x2^3 + 1×2^2 + 0x2^1 + 1×2^0 = 2421

Convert 2421 to Binary

Now you already know the most important thing:

100101110101₁₀ equals 2421₂ if unsigned.

If 2421 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000100101110101 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 2421 signed using two’s complement, will start with one or more 1’s, but the exact code for -2421 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
