Logic gates
The library has XOR,AND,OR,NAND,XNOR, and NOR logic gates.
var funary = require('funary');
funary.gates.and([1,1,1,1,1,0]) //0
funary.gates.and([1,1,1,1,1,1]) //1
funary.gates.xor([0,0,0,0,1,0]) //1
funary.gates.xor([1,0,0,0,0,1]) //0
funary.gates.or([0,0,0,0,0,1]) //1
funary.gates.or([0,0,0,0]) //0
Bitwise operations & bit shifts
Bitwise operations and bit shifts for bit manipulation.
var funary = require('funary');
//Bitwise operations. Similar selection to gates. AND,OR , ... etc.
funary.bitwise.and([0,1,0,1,0,1,0,1,1,1],[1,0,0,0,1,1,1,1,0,1]) //[0,0,0,0,0,1,0,1,0,1]
