(Bilgisayar) Arabellek altaşımı (ıng. buffer underrun ve ya buffer underflow): Bilgi işlemde iki cihaz ve ya işlem ile haberleşmede kullanılan arabelleğe, verinin okuma hızından daha düşük bir hızla beslenmesi durumudur. Bu durum, arabellekten okuma yapan program ve ya cihazın arabellek tekrar doldurulurken işlemini durdurmasını gerektirir ve arabelleğe konulan verinin genellikle böyle işlem başlama ve durdurma erişimlerine uygun olmaması nedeniyle istenilmeyen ve bazen çok önemli yan etkilere neden olabilir
A condition in which the value of a computed quantity is smaller than the smallest non-zero value that can be physically stored; usually treated as an error condition
(Bilgisayar) A data-processing error arising when the absolute value of a computed quantity is smaller than the limits of precision of the computing device, retaining at least one significant digit
the dominant flow of two confronting flows, over the other The lesser flow reverses direction giving poor surface appearance and structural strength Underflow should be avoided by positioning gates so that the flow fronts meet at the end of filling
An exception condition caused by passing a floating-point value that is lower than the lowest valid floating-point value See min_float for additional information
(ISO) The state in which a calculator shows a zero indicator for the most significant part of a number while the least significant part of the number is dropped For example, if the calculator output capacity is four digits, the number 0000432 will be shown as 0000 See: arithmetic underflow [10]
In computing, a condition occurring when a machine calculation produces a non-zero result that is smaller than the smallest non-zero quantity that the machine's storage unit is capable of storing or representing
An error condition occurring when the result of an arithmetic operation yields a result that is smaller than the minimum value in the range of a data type For example, in unsigned arithmetic, underflow occurs when a result is negative See also denormalized number (Alpha)
