Binary 41 = 1010012
The binary for 41 is 101001

As any other integer, 41 can be written as sum of potencies to the power of 2, known as binary code. Here’s the proof that 101001 is the binary of 41:

1×2^5 + 0x2^4 + 1×2^3 + 0x2^2 + 0x2^1 + 1×2^0 = 41

## Convert 41 to Binary

Now you already know the most important thing about 41 in binary form. 101001 is binary 41. That is if the binary in unsigned.

If 41 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000101001 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 41 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 41 signed using two’s complement, will start with one or more 1’s, but the exact code for -41 decimal to binary depends on the signed number representation system and number of bits available.
