<s>[INST] 17539 decimal to binary not getting the same result I'm trying to convert 17539 to binary. My math says its 110000010010001, but online calculators like this and this say it equals to 100010010000011. Who is making something wrong.
 [/INST] Note that 
$$\begin{align}
17539 &= \color{red}1\cdot 2^{14}+ \color{red}0\cdot2^{13} + \color{red}0\cdot2^{12} +\color{red}0\cdot2^{11}+ \color{red}1\cdot 2^{10} \\ &+ \color{red}0\cdot2^{9} + \color{red}0\cdot2^{8} + \color{red}1\cdot 2^7 + \color{red}0\cdot2^{6} + \color{red}0\cdot2^{5} \\&+ \color{red}0\cdot2^{4} +\color{red}0\cdot2^{3} +\color{red}0\cdot2^{2} +\color{red}1\cdot 2^1 + \color{red}1\cdot 2^0.
\end{align}
