Description:
------------
Hi. I wrote these lines for the PHP 7.3.5

these codes must return 13495 but return 13494.
I try with the intval function and the result is the same as before.
but when I use the round function it returns the correct answer.

I tested by any PHP version in Linux, Windows, and other online PHP testers.

thanks
RezaAb

Test script:
---------------
$no = 134.95;
$number = (int)($no*100);
echo $number;//print 13494

Expected result:
----------------
13495

Actual result:
--------------
13494

Floating point values have a limited precision. Hence a value might
not have the same string representation after any processing. That also
includes writing a floating point value in your script and directly
printing it without any mathematical operations.

If you would like to know more about "floats" and what IEEE
754 is, read this:

Thank you for your interest in PHP.

Using round() is the solution.
