Convert 138 to Binary

Now you already know the most important thing about 138 in binary form. 10001010 is binary 138. That is if the binary in unsigned.

If 138 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00010001010 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 138 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 138 signed using two’s complement, will start with one or more 1’s, but the exact code for -138 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 138 is on other number systems, we have that too:
