Convert 42485 to Binary

Now you already know the most important thing:

1010010111110101₁₀ equals 42485₂ if unsigned.

If 42485 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 0001010010111110101 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 42485 signed using two’s complement, will start with one or more 1’s, but the exact code for -42485 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
