I'm having trouble figuring out why subtraction of two floats are giving
me a very small number. I'm thinking it has something to do with the
internals of type casting, but i'm not sure. If anyone has seen this or
can give me some suggestions, please.
I have 2 variables that go through a while
Eric,
It sounds like you just need to do some reading on best practices of
security when writing php code. It's pretty vast what one can do when
trying to hack a php application and depending on what php server
settings are set, you may need to do certain things. I'd suggesting
reading / google
* 1;
print $a.br; // 18.49
var_dump($a); // float(18.49)
var_dump($a-18.49); // float(3.5527136788005E-15)
?

I think what you are looking for is a combination of programs. A
mailing list that customers can view answers of emails try mailman or
smartlist. Perhaps just a mailint list would give you want you want.
If you are looking for more of a trouble ticket program, or FAQ program
there are serveral

X you like.
Or you can look at something like BC_MATH where precision can be carried
out as far as you like...
But what you are seeing is to be expected.
That's just the way computers work, basically.

or use the bcmath extension, although for monetary
values you should go perfectly fine with using round(...,2)
on your final results
