Hash arrays of numbers into a string from which you can reconstruct the original values, with configurable precision loss. The generated hashes sort well, so similar input values cause large shared prefixes in hashes.
== 'w07w1z0gs3y0';== 'w07x1e1cs2yk';
Hash the array
[10, -10, 10] and then restore it, using differend
var sortable = ;var hash = sortable;// => 'p4pp5e9cbbuk'sortable;// => [ 9.999942779541016,// -9.999942779541016,// 9.999942779541016 ]var biggerHash = sortable;// => 'p4pp5e9cbbukqnpp5e9cbbukqnpp5e9cb3h'sortable;// => [ 10, -10, 10 ]
Hash the array
values, which may only contain Numbers in the range of
options can either be an object with those possible keys:
precision: Length of the resulting hash
or a Number, in which case it sets
string into an Array of Numbers.
numValues needs to be the number
of elements initially passed to
With npm do:
$ npm install sortable-hash
This is the idea of geohashes generalized for use with all numeric data and numbers of input fields.
