Hi all, I have tried the following script: $val = 10000000000; if (is_int($val)) { echo $val; } else { echo "$val is not an integer\n"; } The answer is: 10000000000 is not an integer. Why does this happen? I use PHP 5. Isn't PHP able to work with values like 10 billion? Do I need to use a certain special class for dealing with big numbers? How can I use that class? Thank you. Teddy reply it's treated as a double since integers have a max value of (-2e32 +1 up to) 2e32-1, which is 4,294,967,296 (4 billion and some). However, you shouldn't really see any difference in working, it's just treated as a double inside (a double float, that is). Which means it'll be written like 1.0e10 internally
