Yes I did > +2147483648 is: 10000000 00000000 00000000 00000000. > -2147483648 is too large to be represented by a signed integer (as it > would be ~(+2147483648) + 1, No, -2147483648 is the lower bound and 2147483647 is the upper bound for signed integers. -2147483648 = 10000000000000000000000000000000 2147483647 = 01111111111111111111111111111111 it still doesn't explain the FPE here. What does explain it is that -2147483648 / -1 = 2147483648 which is too large. Derick -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
