157₁₀ = 10011101₂
Decimal 157 = 10011101 Binary

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

Here’s the proof that 10011101 is the correct result:

1×2^7 + 0x2^6 + 0x2^5 + 1×2^4 + 1×2^3 + 1×2^2 + 0x2^1 + 1×2^0 = 157

Convert 157 to Binary

Now you already know the most important thing:

10011101₁₀ equals 157₂ if unsigned.

If 157 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00010011101 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 157 signed using two’s complement, will start with one or more 1’s, but the exact code for -157 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
