Although the IEEE commonplace defines the essential floating-level operations to return a NaN if any operand is a NaN, this won’t always be one of the best definition for compound operations. For example when computing the suitable scale factor to use in plotting a graph, the utmost of a set of values must be computed.
The preceding examples shouldn’t be taken to suggest that extended precision per se is dangerous. Many programs can benefit from prolonged precision when the programmer is able to use it selectively. Unfortunately, present programming languages do not provide enough means for a programmer to specify when and the way prolonged precision ought to be used. To point out what help is required, we think about the ways by … Read More
