 Have you ever imagined we could convert decimal to binary using an expression? Well no, we always use a `long division` like method ,see Fig.1 Fig.1:  image source Is there a computer expression? Before that lets see some interesting patterns of binary ,see Fig.2 Fig.2 notice the image carefully As you can see  in row 1 patern goes like 0,1,0,1,0,1,0,1 because row 1 is for [place holder 1 -top to bottom] in row 3 patern goes like 0,0,0,0,1,1,1,1 because row 3 is for [place holder 4-top to bottom] Note: I mean rows as from right to left The expression! Values Here: Number: 0-infinity (a value to be converted to binary) binary holder: 1 / 2 / 4 / 8 / 16 / 32 / ... (Place of binary needed, just like tens, hundreds) Result: 0 or 1   Is it not interesting when there is no if condition, and we can get 0 or 1 with just a simple expression? Expression in words: expression 1:   [the number, subtracted from ( reminder we get ,when we divide the same number by binary holder)] note that, resu
