## Convert 21673 to Binary

Now you already know the most important thing about 21673 in binary form. 101010010101001 is binary 21673. That is if the binary in unsigned. If 21673 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000101010010101001 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 21673 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example. Therefore, minus 21673 signed using two’s complement, will start with one or more 1’s, but the exact code for -21673 decimal to binary depends on the signed number representation system and number of bits available.
