WebMar 31, 2016 · Wolfram Alpha gives an answer to this integral with some strange erf thing. Surely it is quite clear that there is an answer to this, and it is I = − 1 2 x e − x 2. This can be seen because d d x ( − 1 2 x e − x 2) = − 1 2 x ( − 2 x) e − x 2 = e − x 2 and by considering the fundamental theorem of calculus. calculus Share Cite Follow WebA reasonable bound for an accurate implementation would be 4 ulps, corresponding to the accuracy bound of the math functions in the LA profile of Intel's Vector Math library, which I have found to be a reasonable bound for non-trivial math function implementations that require both good accuracy and good performance.
