Abstract:
For efficient computation of results for mathematical functions, a method receives a mathematical function call. The call includes a plurality of arguments for which a range of computable results for the mathematical function of the function call varies with respect to the values for the arguments. The method determines whether executing the mathematical function using the plurality of arguments will produce a result within the range of computable results. The method further aborts the mathematical function call prior to initiating execution of the mathematical function in response to determining that the values for the plurality of arguments produce a result outside the range of computable results.
