This also includes the (int) cast operation, and the following functions: intval() (where the base is 10), settype(), decbin(), decoct(), and dechex() Previous Comments: ------------------------------------------------------------------------ [2017-02-25 18:10:04] stephin at stephin dot in Description: ------------ php -r "echo intval('1e10');" expected output: 1 actual output: 10000000000 i have tested this in some of other previous version series and found only php 7.1.x have this bug. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74167&edit=1
