i found the culprit. i remembered, that i use to pass the value with..
number_format($totalCost, 2, ".", ",")
so the values being received by my computation has a "," comma 4,000
so that is why i always get wrong values.
thanks again!

Howdy.
It seems to work fine for me, perhaps you have a typo along the lines

'don't know what's "the pecent of 20% is" ;) but in decimal
form, yes, it's right. Or, just ".2" or "0.2".

Gee! I forgot the '$'. It's been right there in my face. Thanks! I hope
the round() function work without a problem because I saw in some posting
that some people have this problem where if 3.51 is rounded, it return a 3.

The int() function is for C/C++ programming only. This Int() function is
not supported in PHP. In PHP it would be Intval(). For float, Floatval().
For double, DoubleVal(). Etc. But beware of the Octual numbers.

I used your snip you just posted and changed the $Days = round(Days) to
$Days = round($Days) and got 228.
