PARI-Primecount
This is a PARI/GP interface to the primecount library which may allow bigger prime counts and n'th prime than native PARI.
Functions are named per the library, so for instance
-
primecount_pi()equivalent to PARIprimepi() -
primecount_nth_prime()equivalent to PARIprime()
The interface is a C wrapper which must be compiled and which
primecount.gp loads with install(). If
you don't have a C compiler then primecount.gp runs
the primecount program instead. See comments in
primecount.gp for further notes.
