Question

This is killing me! I’ve never had so much trouble and I can’t figure out what I’m doing wrong here.

If I have a number, say 2.32, and I want to do math with it it won’t work out. The very simplest example:

$income = $commission; //Commission is 2.32, retrieved from XML
echo "income: $income<br>";
$income100 = $income*100;
echo "income100: $income100<br>";

The result I get is:

income: 2.32
income100: 200

How can I use a decimal number accurately with math without it changing it?

Thanks so much!

Answer 1

You need to assign $income in the following manner to get rid of the underlying SimpleXMLElement:

$income = (float) $commission;

Example of what happens when you don’t:

$x = simplexml_load_string("<a>2.4</a>");
echo $x * 100; // output:  200
