## What is Underflow? - Definition from Techopedia

Underflow is a condition which occurs in a computer or similar device when a mathematical operation results in a number which is smaller than what the device is capable of storing. It is the opposite of overflow, which relates to a mathematical operation resulting in a number which is bigger than what the machine can store. Similar to ...

## Arithmetic Overflow and Underflow — Blog

Oct 13, 2018· On underflow, we would stop at the smallest representable value. In our 8-bit signed integer example, we would now have 127 + 1 be 127 and -128 - 1 be -128. There are several advantages with this approach: for one, the resulting values on overflow and underflow are the closest to the "real" values we would get if operating without constraints.

## Binary Overflow | Binary Arithmetic | Electronics Textbook

Binary Overflow Chapter 2 - Binary Arithmetic PDF Version. One caveat with signed binary numbers is that of overflow, where the answer to an addition or subtraction problem exceeds the magnitude which can be represented with the alloted number of bits. Remember that the place of the sign bit is fixed from the beginning of the problem.

## Integer overflow - Wikipedia

Usage varies as to whether a saturation is or is not an overflow. To eliminate ambiguity, the terms wrapping overflow and saturating overflow can be used. The term underflow is most commonly used for floating-point math and not for integer math. But, many references can be found to integer underflow.

## Arithmetic underflow - Wikipedia

underflow depends exclusively upon the given algorithm and the given input data,and hence there is no direct control by the programmer .Overflow on the other hand, depends upon the arbitrary choice of the programmer for the amount of memory space reserved for each stack,and this choice does influence the number of times overflow may occur

## Java Overflow And Underflow - Javapapers

Overflow and underflow is a condition where you cross the limit of prescribed size for a data type. When overflow or underflow condition is reached, either the program will crash or the underlying implementation of the programming language will have its own way of handing things.

## DB2 10 - Codes - SQLCODE -413

-413 OVERFLOW OR UNDERFLOW OCCURRED DURING NUMERIC DATA TYPE CONVERSION. Explanation. During processing of the SQL statement, an overflow or underflow condition arose when converting from one numeric type to another. Numeric conversion is performed according to …

## Arithmetic underflow - Wikipedia

The term arithmetic underflow (or "floating point underflow", or just "underflow") is a condition in a computer program where the result of a calculation is a number of smaller absolute value than the computer can actually represent in memory on its central processing unit (CPU).

## terminology - Is INT_MIN-1 an underflow or overflow ...

In integer math, overflow refers to both too-large and too-small values. In floating point, overflow refers to too large an exponent, and underflow refers to too small an exponent. In fact, for integer types, CPUs have no way to tell the difference between overflow and underflow. Take the following 16-bit add:
