==Wolfram Mathworld and Perl==
I copied one of the equations, <code>|sin(pi x2)| > 1/2, 0 < x < 10</code> into [http://www.wolframalpha.com/input/?i=%7Csin%28pi+x2%29%7C%3E1%2F2%2C+0+%3C+x+%3C+10 mathworld] and got the result:
:<code>sqrt(12 * n + 1) / sqrt(6) < x < sqrt(12 * n + 5) / sqrt(6), 0 <= n <= 49</code>
For n = 49 I get the range component: (9.9079092984679, 9.941495528004495) which differs from the Perl: (9.96, 9.99). --[[User:Paddy3118|Paddy3118]] 07:04, 2 October 2011 (UTC)
