## Convert 21051 to Binary

Now you already know the most important thing about 21051 in binary form. 101001000111011 is binary 21051. That is if the binary in unsigned.

If 21051 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000101001000111011 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 21051 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 21051 signed using two’s complement, will start with one or more 1’s, but the exact code for -21051 decimal to binary depends on the signed number representation system and number of bits available.
