Given, say, 1.25 - how do I get "1" and ."25" parts of this number?
I need to check if the decimal part is .0, .25, .5, or .75.
$n = 1.25;
$whole = floor($n); // 1
$fraction = $n - $whole; // .25
Then compare against 1/4, 1/2, 3/4, etc.
In cases of negative numbers, use this:
function NumberBreakdown($number, $returnUnsigned = false)
{
$negative = 1;
if ($number < 0)
{
$negative = -1;
$number *= -1;
}
if ($returnUnsigned){
return array(
floor($number),
($number - floor($number))
);
}
return array(
floor($number) * $negative,
($number - floor($number)) * $negative
);
}
The $returnUnsigned
stops it from making -1.25 in to -1 & -0.25
