The binary for 265 is 100001001

As any other integer, 265 can be written as sum of potencies to the power of 2, known as binary code. Here’s the proof that 100001001 is the binary of 265:

1×2^8 + 0x2^7 + 0x2^6 + 0x2^5 + 0x2^4 + 1×2^3 + 0x2^2 + 0x2^1 + 1×2^0 = 265

Now you already know the most important thing about 265 in binary form. 100001001 is binary 265. That is if the binary in unsigned.

If 265 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000100001001 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 265 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 265 signed using two’s complement, will start with one or more 1’s, but the exact code for -265 decimal to binary depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal. If you like to know what decimal 265 is on other number systems, we have that too:
