Abstract

An apparatus and system are provided for efficient computation of reliable results for mathematical functions. The apparatus may include an interface, a control module, and an error module. The interface receives a mathematical function call. The call includes a plurality of arguments for which a range of computable results for the mathematical function varies with respect to the values for the arguments. The control module determines whether executing the mathematical function using the plurality of arguments will produce a result within the range of computable results. The error module 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.
