* fix(range): consistently convert min & max to numbers

Basically we had two methods to turn a number (or string) into a precision:

1. Math.floor(min * pow) / pow
2. Number(Number(v).toFixed(precision))

these behave different for precision 0 & a number over .5, let's say 1.5 turns into 1 for method 1, and into 2 for method 2. This is a bug (not caught by most of our tests, notably the ones i had to change) and causes the range to change to a number it's not supposed to be. Pay special attention to the new `toPrecision` utility, and the places it was used.

At the same time I also converted to TypeScript, but not the components themselves, since that was too much work.

typescript for tests is expected to fail until algolia/algoliasearch-client-javascript#1229 is released (since now certain parts aren't random objects, but rather search responses)

The version for the helper is bumped for better typescript support as well.

update types

requires algolia/algoliasearch-client-javascript#1234

update client for fix in typing for tests

update assertions in changed tests

clarify why behaviour is like it is

* address feedback

* integrate fix from the helper avoiding workaround here

  • Customize your components at will
  • Remain independent from external frameworks

Getting started

Using InstantSearch.js is as simple as adding this JavaScript code to your page:

// 1. Instantiate the search
const search = instantsearch({
  indexName: 'instant_search',
  searchClient: algoliasearch('latency', '6be0576ff61c053d5f9a3225e2a90f76'),

  // 2. Create an interactive search box
    container: '#searchbox',
    placeholder: 'Search for products',

  // 3. Plug the search results into the product container
    container: '#products',
    templates: {
      item: '{{#helpers.highlight}}{ "attribute": "name" }{{/helpers.highlight}}',

  // 4. Make the brands refinable
    container: '#brand',
    attribute: 'brand',

// 5. Start the search!
