We develop fast and accurate algorithms for evaluating √x 2 +y 2 for two floating-point numbers x and y . Library functions that perform this computation are generally named hypot(x,y). We compare five approaches that we will develop in this article to the current resident library function that is delivered with Julia 1.1 and to the code that has been distributed with the C math library for decades. We will investigate the accuracy of our algorithms by simulation.

我们开发了快速准确的算法来评估√x2+y2对于两个浮点数X和是的. 执行此计算的库函数通常命名为 hypot(x,y)。我们将在本文中开发的五种方法与 Julia 1.1 提供的当前常驻库函数以及几十年来随 C 数学库分发的代码进行比较。我们将通过仿真研究我们算法的准确性。
