trit-getset

Get and set trits (base 3 digits) of a signed integer

Usage:

var get_trit = require('trit-getset').get_trit;
var clear_trit = require('trit-getset').clear_trit;
var set_trit = require('trit-getset').set_trit;
var slice_trits = require('trit-getset').slice_trits;

get_trit(n,i);      // get value of ith trit of n (0=least significant)

clear_trit(n,i);    // set ith trit to 0

set_trit(n,i,t);    // set ith trit to t=-1, 0, or 1

slice_trits(n,a,b); // extract trits of n from range a to b

Trits are a base 3 digits, analogous to bits (for base 2). This module supports balanced ternary (see also: balanced-ternary).

All inputs (n) are signed integers. i and a or b indices are from the least significant trit (lst) at 0. See test.js for more examples.
