Overflow and Underflow Overflowis said to occur when the number that one gets as a result of some arithmetic operation on twon-bit binary numbers (signed or unsigned) is larger inmagnitudethan the largest number one can represent usingn-bits. What if the operation of two numbers yields a num...
Underflow in floating-point numbers occurs when the precision of a value is compromised due to its placement beyond the decimal point. In the IEEE 754 standard for single-precision floating-point numbers, the significand has 23 bits, and the location of the decimal point is determined by the e...
As overflow will result in either positive or negative infinity, and underflow in a positive or negative zero, we do not need exact arithmetic methods like for the integer data types.Instead, we can check for these special constants to detect over- and underflow. If we want to throw an exc...
By using bit fields sufficiently large to handle the magnitude of the sums, we arrive at the correct answers. In these sample problems we’ve been able to detect overflow errors by performing the addition problems in decimal form and comparing the results with the binary answers. ...
We test the arithmetic overflow and underflow of floating point special numbers in different CPUs. The experimental results indicate the floating point overflow exists in many kinds of language programs and binary executable software.Jianjun Chen
If you don't specify the overflow-checking context, the value of the CheckForOverflowUnderflow compiler option defines the default context for non-constant expressions. By default the value of that option is unset and integral-type arithmetic operations and conversions are executed in an unchecked ...
Furthermore, arithmetic overflow and underflow effects must be examined. It cannot be over-emphasized how important this design step is, especially for IIR filters. While FIR filters are guaranteed to be stable, IIR filters can exhibit instability due to quantization errors introduced in the ...
Stack caching method with overflow/underflow control using pointers The present invention uses a stack management unit including a stack cache to accelerate data retrieval from a stack and data storage into the stack. In one embodiment, the stack management unit includes a stack cache, a dribble ...
