Previous Comments: ------------------------------------------------------------------------ [2011-07-01 03:09:47] aharvey@php.net 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: http://www.floating-point-gui.de/ Thank you for your interest in PHP. Integers beyond PHP_INT_MAX are silently converted to floats, and float equality is, as the above blurb says, interesting. ------------------------------------------------------------------------ [2011-07-01 03:00:33] mati at we dot ee Description: ------------ echo in_array(9440385200600001069, array(9440385200600001036)) .
