215₁₀ = 11010111₂
Decimal 215 = 11010111 Binary

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

Here’s the proof that 11010111 is the correct result:

1×2^7 + 1×2^6 + 0x2^5 + 1×2^4 + 0x2^3 + 1×2^2 + 1×2^1 + 1×2^0 = 215

Convert 215 to Binary

Now you already know the most important thing:

11010111₁₀ equals 215₂ if unsigned.

If 215 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00011010111 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 215 signed using two’s complement, will start with one or more 1’s, but the exact code for -215 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
