round down

[sandrob57]

need some quick variable help.

 

$points

$loans_open

$loans_max

$loans_left

 

Those are the variable we will be working with. basicaly, for every 25 points I want someone to allowed a new loan.

 

So lets say $points = 110 and $loans_open = 1.

 

That means you have 110 points, which allows for 4 loans.

 

Then you 1 current loan open, so you can purchase 3 more.

 

I'm not realy sure how to get the $loans_max variable.

 

Sure I could go $points / 25, but that would give me 4.4

 

How do I make it so 4.4 rounds down to 4? Thanks.

never mind

The only problem is that 4.5 to 4.9999999 would round UP.

 

Remember that a number is treated as a string in PHP.  Use that to your advantage:

 

$nums = explode(".", $decimal);//  <--This will split the decimal number into an array.  Element #0 will be the whole number portion and element #1 will be the decimal portion.
$wholeNum = $nums[0];

floor ($points / 25);

Round a float to the nearest integer:

 

$nearest = (int) ($float + .5);

 

No need to call a function.

 

In your case you'd want to do:

 

$loan_max = (int) ($points / 25);

I would suggest using floor also, as posted by Barand

[ted_chou12]

yeah, i suggest floor() as well.

It doesn't really matter- they both will give the same result.

 

You can maybe say that using floor() is more clear, but it doesn't matter.

From the other side, I think using casting (using (int)) will be a little bit faster, but even if it is- the difference will be ridiculously small.

I agree and I'm closing this before it becomes a poll
