Question

Im parsing xml using php and one of my variables receive a long decimal value.

$ctr = 0.00529440333938;

But I need to make this number as 0.52%, so I tried multiplying by 100 and forcing just 2 decimals.

$real_ctr = $ctr * 100;
echo number_format($real_ctr, 2) . "%";

I get as result 0.00% instead 0f 0.52%

And then I tried adding 1 just for testing purpose

$real_ctr = $ctr + 1;

and I get as result 0.005294403339381. It adds 1 at the end.

Any suggestions how can I get around this issue?

Answer 1

It seams $ctr what you get from the XML parser is a string. Use:

$ctr = floatval($ctr); // or (double)$ctr; or (float)$ctr;

to make sure your variable is a float.
