Decimal 126 = 1111110 Binary


Any integer can be written as sum of potencies to the power of 2, known as binary code.

Here’s the proof that 1111110 is the correct result:

1×2^6 + 1×2^5 + 1×2^4 + 1×2^3 + 1×2^2 + 1×2^1 + 0x2^0 = 126

Now you already know the most important thing:

111111010 equals 1262 if unsigned.

If 126 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 0001111110 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 126 signed using two’s complement, will start with one or more 1’s, but the exact code for -126 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
