Integer overflow/underflow

Official Description It is an error if an integer operation or function is not performed according to the mathematical rules for integer arithmetic.

Simplified Description

This appears to mean that it is an error if integer operations or functions overflow or underflow. So for example


should be an error since

   maxint = 2,147,486,647

but due to integer overflow

   maxint+maxint = -2

Error Handling

This error is never reported.
