Convert 31405 to Binary

Now you already know the most important thing:

111101010101101₁₀ equals 31405₂ if unsigned.

If 31405 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 000111101010101101 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 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 31405 signed using two’s complement, will start with one or more 1’s, but the exact code for -31405 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
