Numeric Exceptions
Structured Exception Handling was added in INtime 4, then extended for floating-point exceptions in INtime 6. It is recommended to use SEH instead of explicit exception handlers.
Floating point exceptions must be enabled in SEH.
A numeric exception occurs when floating point calculations give an improper result, such as a floating-point divide by zero. SSE (Streaming SIMD (Single Instruction, Multiple Data) Extensions) instructions can also result in numeric exceptions.
These exceptions can be handled by an explicit exception handler. While the system always provides an exception handler with standard functionality, a thread can set an individual handler customized for its specific requirements.
