Binary 38 = 1001102
The binary for 38 is 100110

As any other integer, 38 can be written as sum of potencies to the power of 2, known as binary code. Here’s the proof that 100110 is the binary of 38:

1×2^5 + 0x2^4 + 0x2^3 + 1×2^2 + 1×2^1 + 0x2^0 = 38

## Convert 38 to Binary

Now you already know the most important thing about 38 in binary form. 100110 is binary 38. That is if the binary in unsigned.

If 38 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000100110 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 38 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 38 signed using two’s complement, will start with one or more 1’s, but the exact code for -38 decimal to binary depends on the signed number representation system and number of bits available.
