java - Difference between Math.IEEEremainder() and StrictMath.IEEEremainder() -

-

i found ieeeremainder() @ 2 places in lang package.

  1. java.lang.math.ieeeremainder()
  2. java.lang.strictmath.ieeeremainder()

my question both methods same or different?

as spelled out in documentation:

unlike of numeric methods of class strictmath, implementations of equivalent functions of class math not defined return bit-for-bit same results. relaxation permits better-performing implementations strict reproducibility not required.

since x86(-64) architecture uses ieee 754 floating-point, on x86 openjdk implementation, math tends delegate strictmath, , in case, not required specification.

-
realizing i'm going take beating this, have several questions "best practices" when constructing laravel route. do laravel routes run "first come first serve" top bottom? if route found, pass control controller (or perform action) , terminate? i have part of application acts url shortner. so, route looks this: route::get('/{id}', array('as' => 'home.text', 'uses' => 'homecontroller@text'), function($id){ //make sure id exists before pushing controller. if (storage::where('shortcode','=', $id)->count() > 0) { // route found } }); how can improved? one, i'm not sure how pass processing on controller conditionally.. sort of controller::make() ..? 3) there better way in laravel check if record exists versus doing mode::where('column','=','value')->count() 4) have legacy urls http://url.com/?...
