Ramanujan's constant

From Wikipedia, the free encyclopedia

Ramanujan's constant is the transcendental number e^{\pi \sqrt{163}}.

Its value is extraordinarily close to an integer:

262,537,412,640,768,743.999\ 999\ 999\ 999\ 25\ldots [1]

It was discovered in 1859 by the mathematician Charles Hermite.[2] In a 1975 April Fool article in Scientific American magazine [3], columnist Martin Gardner made the (hoax) claim that the number was in fact an integer, and that the Indian mathematical genius Srinivasa Ramanujan had predicted it — hence its name.
