Some Floor, Ceil, Round issues

TheMayhem

  $nehtotal = (time() - $neh[datewon]) / 86400;

  $nehhours = $nehtotal / 3600;
  $nehminutes = $nehhours / 60;

  $nehdays = floor($nehtotal);

It's a pretty basic script. Right now it is outputting this.

0 days
1.7316100823045E-05 hours
2.8860168038409E-07 minutes

My problem is when it comes to rounding basically if the number is 0 and then decimals after it, I want it to be a 0, same with 1, same with 2. I tried using the floor function on for example minutes, but everything I floor it with returns back a value of 0. In matter of fact the only way I can figure out hours and minutes is if I leave it in a long decimal format and well I just don't want that. I want to take the base number and loose the decimals but can't seem to figure out how to do it, and also what are those -05 and -07 things at the end mean?

You can try just casting the variable as an integer if you just want to truncate the decimials.

$floor = (int)$some_float

The E-07 type numbers are in scientific notation. 2.5E-02 translates to 2.5 x 10^(-2) or 0.025.

That makes them a 0 🙁

PHP wise I dunno if I've discovered a bug or what but this makes no sense.

   $nehminutes = ((($time - $neh[datewon]) / 86400) / 3600) / 60;
// This outputs 3.6625514403292E-06 minutes


   $nehminutes = ceil(((($time - $neh[datewon]) / 86400) / 3600) / 60);
// This outputs 1

It's like the ceil function is not exhisting in this entire query and pretty much driving me insane. If I have a number that is 3.6 how can I use a ceil function and it be reduced to 1? It's not php possible 🙁!!!!!!!!!!!

3.6625514403292E-06 is not 3.6...; it's .0000036...
"ceil(.0000036)" equals 1.

PHP is working right, you're just producing very small numbers between 0 and 1. So when you floor them it will become 0.
