145₁₀ = 10010001₂
Decimal 145 = 10010001 Binary

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

Here’s the proof that 10010001 is the correct result:

1×2^7 + 0x2^6 + 0x2^5 + 1×2^4 + 0x2^3 + 0x2^2 + 0x2^1 + 1×2^0 = 145

Convert 145 to Binary

Now you already know the most important thing:

10010001₁₀ equals 145₂ if unsigned.

If 145 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00010010001 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 145 signed using two’s complement, will start with one or more 1’s, but the exact code for -145 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
