In subject area: Computer Science An arithmetic expression is defined as a combination of numbers, variables, and arithmetic operators like addition, subtraction, multiplication, division, and power, enclosed in brackets. It can be as simple as a single value or as complex as a large calculation...
Abstract: A previous paper presented an efficient algorithm, called the Recomputation Algorithm, for evaluating a rational expression to within any desired tolerance on a computer which performs variable-precision aritbmetic operations. The Recomputation Algorithm can be applied to expressions involving an...
For example, the expression (2.5 × 10-3) × (4.0 × 102) involves only a single floating-point multiplication.FIGURE D-1 Normalized numbers when = 2, p = 3, emin = -1, emax = 2Relative Error and Ulps Since rounding error is inherent in floating-point computation, it is important...

operations). The values of all variables will be saved in this area. The address of a variable x is the index in the array where x’s value is saved. symbol table: It is a data structure that supports the following operations:
If the compiler attempts to reorganize this expression as b + d − c, however (e.g., in order to delay its use of c), then arithmetic overflow will occur. Despite our intuition from math, this reorganization is unsafe. Many languages, including Pascal and most of its descendants, ...
The following is an intuitive way to justify the values included in an expression's cset. Consider the function The question is: what is the cset of h(x0), for x0 = 0 ? To answer this question, consider the function Clearly, f(x0) = 0, for x0 = 0. But, what about ...
The regularity of the access pattern and the reuse of data elements between successive iterations of the loop body means that there is a common sub-expression between any two successive iterations; these common sub-expressions are difficult to detect using state-of-the-art compiler technology. If...
