NAME

Math::NumSeq::TotientCumulative -- cumulative totients

SYNOPSIS

 use Math::NumSeq::TotientCumulative;
 my $seq = Math::NumSeq::TotientCumulative->new;
 my ($i, $value) = $seq->next;

DESCRIPTION

The cumulative sum totient(1) to totient(i).

FUNCTIONS

See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.

$seq = Math::NumSeq::TotientCumulative->new ()

Create and return a new sequence object.

Random Access

$value = $seq->ith($i)

Return totient(i).

$bool = $seq->pred($value)

Return true if $value occurs in the sequence, ie. is a sum totient(1) to totient(i) for some i.
