2 questions

Hi,

I have 2 questions:

1) How do I include file? what is the syntax?

2) I have to vars : $a*$b/100 The results is with a lot of number after the point - 12.33232323 how do I display only the number with out the rest?

thanks,
Assaf

include('pathTofile');

floor($a/$b); returns a number without rest.

Beware!

round(3.21); // returns 3
round(3.5); // returns 4
round(3.70); // returns 4

It rounds it

floor(3.21); // returns 3
floor(3.5); // returns 3
floor(3.70); // returns 3

It removes the decimal part without rounding the number

ceil(3.21); // returns 4
ceil(3.5); // returns 4
ceil(3.70); // returns 4

It returns the closest integer bigger than the number given

I would also check out the printf() function, it should allow you to format your output.

I.E.

$some_float = 23.4444445555;
printf("%2.3f", $some_float);

This will dispaly:

23.444

The formating of the above float is two digits before the decimal point and 3 digits after it.
