[[File:TI86 Calculator DivByZero.jpg|thumb|Handheld calculators, such as this [[TI-86]], typically halt and display an error message after an attempt to divide by zero.]]

[[Integer (computer science)|Integer]] division by zero is usually handled differently from floating point since there is no integer representation for the result. [[Central processing unit|CPUs]] differ in behavior: for instance [[x86]] processors trigger a [[Interrupt|hardware exception]], while [[PowerPC]] processors silently generate an incorrect result for the division and continue, and [[ARM architecture family|ARM]] processors can either cause a hardware exception or return zero.<ref>{{citation |title=Divide instructions |work=ARMv7-M Architecture Reference Manual |publisher=Arm Limited |url=https://developer.arm.com/documentation/ddi0403/d/Application-Level-Architecture/The-ARMv7-M-Instruction-Set/Data-processing-instructions/Divide-instructions |access-date=2024-06-12 |edition=Version D |year=2010 }}</ref> Because of this inconsistency between platforms, the [[C (programming language)|C]] and [[C++]] [[programming language]]s consider the result of dividing by zero [[undefined behavior]].<ref> {{cite conference |mode=cs2 |last1=Wang |first1=Xi |last2=Chen |first2=Haogang |last3=Cheung |first3=Alvin |last4=Jia |first4=Zhihao |last5=Zeldovich |first5=Nickolai |last6=Kaashoek |first6=M.
