  2. Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Integer_overflow

    Integer overflow can be demonstrated through an odometer overflowing, a mechanical version of the phenomenon. All digits are set to the maximum 9 and the next increment of the white digit causes a cascade of carry-over additions setting all digits to 0, but there is no higher digit (1,000,000s digit) to change to a 1, so the counter resets to zero.

  3. Year 2038 problem - Wikipedia

    en.wikipedia.org/wiki/Year_2038_problem

    Analogous storage constraints will be reached in 2106, where systems storing Unix time as an unsigned (rather than signed) 32-bit integer will overflow on 7 February 2106 at 06:28:15 UTC. Computer systems that use time for critical computations may encounter fatal errors if the year 2038 problem is not addressed.

  4. Undefined behavior - Wikipedia

    en.wikipedia.org/wiki/Undefined_behavior

    In C the use of any automatic variable before it has been initialized yields undefined behavior, as does integer division by zero, signed integer overflow, indexing an array outside of its defined bounds (see buffer overflow), or null pointer dereferencing. In general, any instance of undefined behavior leaves the abstract execution machine in ...

  5. Arithmetic underflow - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_underflow

    For integers, the term "integer underflow" typically refers to a special kind of integer overflow or integer wraparound condition whereby the result of subtraction would result in a value less than the minimum allowed for a given integer type, i.e. the ideal result was closer to negative infinity than the output type's representable value ...

  6. Arbitrary-precision arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arbitrary-precision_arithmetic

    Some programming languages such as Lisp, Python, Perl, Haskell, Ruby and Raku use, or have an option to use, arbitrary-precision numbers for all integer arithmetic. Although this reduces performance, it eliminates the possibility of incorrect results (or exceptions) due to simple overflow.

  7. Signal (IPC) - Wikipedia

    en.wikipedia.org/wiki/Signal_(IPC)

    The SIGFPE signal is sent to a process when an exceptional (but not necessarily erroneous) condition has been detected in the floating-point or integer arithmetic hardware. This may include division by zero, floating-point underflow or overflow, integer overflow, an invalid operation or an inexact computation. Behaviour may differ depending on ...

  8. Talk:Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Talk:Integer_overflow

    Integer overflow is a special case of arithmetic overflow, which can also include float overflow (too large integer exponent, which again is a type of integer overflow, but is (or may be) handled differently for the exponents of floats (i.e. by assigning the special +Infinity and -Infinity values)).37.44.138.159 07:18, 25 August 2019 (UTC)

  9. Overflow flag - Wikipedia

    en.wikipedia.org/wiki/Overflow_flag

    Overflow cannot occur when the sign of two addition operands are different (or the sign of two subtraction operands are the same). [1] When binary values are interpreted as unsigned numbers, the overflow flag is meaningless and normally ignored. One of the advantages of two's complement arithmetic is that the addition and subtraction operations ...
