rounding float values in javascript can produce undesirable results (i.e. errors in the exponent), although certain situations can still produce inaccuracy, this fixes the common cases, ** use with caution **
// fixes rounding of float values in javascript
Number.prototype.round = function(num_places) {
return +(Math.round(this +'e+'+ num_places) +'e-'+ num_places)
}

/** DEPRECATED **/

website navigation menu

my website is impossible to navigate conventionally...
please use these links:

  • homepage
    • which is also the 404 page (all invalid routes are redirected)
  • a menu (prototype, which turned out to be unsuitable)
  • blog (http_//blog.joat.es) deprecated

for reference: here is the Drupal / PHP version of my Mmmovies project (i think i did this about 2 years ago) it works really well actually, it's quite a lot of code though (at over 1k LoC) in the main file, plus a tiny bit more in the include file.
<?php

/**
