Abstract:
1. An apparatus for efficient computation of results for mathematical functions, the apparatus comprising: an interface comprised of executable code stored on one or more memory devices of a computing device and configured to receive a mathematical function call, the call comprising 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; a control module comprised of executable code stored on one or more memory devices of a computing device and configured to determine whether executing the mathematical function using the plurality of arguments will produce a result within the range of computable results; and an error module comprised of executable code stored on one or more memory devices of a computing device and configured to abort 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.
