NAME
Math::NumSeq::Primorials  primorials 2*3*...*p[i]
SYNOPSIS
use Math::NumSeq::Primorials;
my $seq = Math::NumSeq::Primorials>new;
my ($i, $value) = $seq>next;
DESCRIPTION
The sequence of primorials, being the product of the first i many primes, 2*3*5*...*p[i].
1, 2, 6, 30, 210, ...
starting i=0
FUNCTIONS
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
Random Access
$value = $seq>ith($i)

Return
2*3*5*...*p[$i]
. For$i==0
this is considered an empty product and the return is 1. $bool = $seq>pred($value)

Return true if
$value
is equal to2*3*5*...*p[i]
for number of primes. $i = $seq>value_to_i_floor($value)

Return the index i of
$value
or of the next primorial below$value
. $i = $seq>value_to_i_estimate($value)

Return an estimate of the i corresponding to
$value
.
