I was playing with JavaScript's bit manipulation where i tried "and operation" with various numbers and every time got binary result but for few numbers i am always getting weird decimal number.
10100 & 1000 = 864
864 why?

1`&&` is logical operator, `&` is bitwise operator – ponury-kostek Dec 19 '18 at 14:10

510100 and 1000 are decimal. To force treating them as binary you need to use binary prefix like `0b10100 & 0b1000` – Andrey Dec 19 '18 at 14:13

Thanks... 0b would yield right result. – Vikas Dec 19 '18 at 14:21

&& is logical operator, & is bitwise logical operator
decimal | binary
------------------------
10100 = 10011101110100
1000 = 1111101000
&
864 = 1101100000
As @Andrey mention, if you want to force binary notation use 0b prefix
0b10100 and 0b1000
