Binary 513 = 10000000012
The binary for 513 is 1000000001

As any other integer, 513 can be written as sum of potencies to the power of 2, known as binary code. Here’s the proof that 1000000001 is the binary of 513:

1×2^9 + 0x2^8 + 0x2^7 + 0x2^6 + 0x2^5 + 0x2^4 + 0x2^3 + 0x2^2 + 0x2^1 + 1×2^0 = 513

## Convert 513 to Binary

Now you already know the most important thing about 513 in binary form. 1000000001 is binary 513. That is if the binary in unsigned.

If 513 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 0001000000001 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 513 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 513 signed using two’s complement, will start with one or more 1’s, but the exact code for -513 decimal to binary depends on the signed number representation system and number of bits available.
