Editing E (mathematical constant) (section)

== In computer culture ==

During the emergence of [[internet culture]], individuals and organizations sometimes paid homage to the number {{mvar|e}}.

In an early example, the [[computer scientist]] [[Donald Knuth]] let the version numbers of his program [[Metafont]] approach {{mvar|e}}. The versions are 2, 2.7, 2.71, 2.718, and so forth.<ref>{{Cite journal

In another instance, the [[Initial public offering|IPO]] filing for [[Google]] in 2004, rather than a typical round-number amount of money, the company announced its intention to raise 2,718,281,828 [[USD]], which is {{mvar|e}} billion [[United States dollar|dollars]] [[rounding|rounded]] to the nearest dollar.<ref>{{Cite journal |last1=Roberge |first1=Jonathan |last2=Melançon |first2=Louis |date=June 2017 |title=Being the King Kong of algorithmic culture is a tough job after all: Google's regimes of justification and the meanings of Glass |url=http://journals.sagepub.com/doi/10.1177/1354856515592506 |journal=Convergence: The International Journal of Research into New Media Technologies |language=en |volume=23 |issue=3 |pages=306–324 |doi=10.1177/1354856515592506 |issn=1354-8565}}</ref>

Google was also responsible for a billboard<ref>{{cite web|url=http://braintags.com/archives/2004/07/first-10digit-prime-found-in-consecutive-digits-of-e/|title=First 10-digit prime found in consecutive digits of {{math|e}}|website=Brain Tags|access-date=2012-02-24|archive-url=https://web.archive.org/web/20131203102744/http://braintags.com/archives/2004/07/first-10digit-prime-found-in-consecutive-digits-of-e/|archive-date=2013-12-03}}</ref>
that appeared in the heart of [[Silicon Valley]], and later in [[Cambridge, Massachusetts]]; [[Seattle, Washington]]; and [[Austin, Texas]]. It read "{first 10-digit prime found in consecutive digits of {{mvar|e}}}.com". The first 10-digit prime in {{mvar|e}} is 7427466391, which starts at the 99th digit.<ref>{{cite web

It turned out that the sequence consisted of 10-digit numbers found in consecutive digits of {{mvar|e}} whose digits summed to 49. The fifth term in the sequence is 5966290435, which starts at the 127th digit.<ref>[http://explorepdx.com/firsten.html The first 10-digit prime in {{math|e}}] {{Webarchive|url=https://web.archive.org/web/20210411010312/http://explorepdx.com/firsten.html |date=2021-04-11 }}.
