Practical implementations Unlike many other functions, such as a Normal Distribution, no obvious fast, accurate implementation that is easy to implement for the Gamma Function is easily found. Therefore, it is worth investigating potential solutions. For the case that speed is more important than accuracy, published tables for are easily found in an Internet search, such as the Online Wiley Library. Such tables may be used with linear interpolation. Greater accuracy is obtainable with the use of cubic interpolation at the cost of more computational overhead. Since tables are usually published for argument values between 1 and 2, the property may be used to quickly and easily translate all real values and into the range , such that only tabulated values of between 1 and 2 need be used.
