INTERRUPT AND EXCEPTION HANDLING
Interrupt 0—Divide Error Exception (#DE)
Exception Class Fault.
Description
Indicates the divisor operand for a DIV or IDIV instruction is 0 or that the result
cannot be represented in the number of bits specified for the destination operand.
Exception Error Code
None.
Saved Instruction Pointer
Saved contents of CS and EIP registers point to the instruction that generated the
exception.
Program State Change
A program-state change does not accompany the divide error, because the exception
occurs before the faulting instruction is executed.
