Our university will have a core network upgrade on Saturday, June 1, beginning at 6 AM CDT (11 AM UTC/GMC).
The outage should last less than four hours. Chris Caldwell (email@example.com)
Welcome to the Nth Prime Page!
Here's how it works: Enter a value for n below,
from 1 to 1012, inclusive. The server will return the
nth prime number (counting 2 as the first). Commas and
scientific notation (e.g. 1.0e12) are allowed. For example,
entering either 1,000,000,000,000 or 1.0e12 will tell you '
1,000,000,000,000th prime is 29,996,224,275,833.' Depending
on the load of the server and the number you pick, your query may take up
to 10 seconds.
Enter a value for x below, from 1 to
3*1013. The server will return pi(x), the number
of primes not exceeding x. For example, entering
29,996,224,275,833 will tell you '
There are 1,000,000,000,000 primes
less than or equal to 29,996,224,275,833.'
