NAME

6       Math::NumSeq::DigitSum -- sum of digits, possibly with powering
7

SYNOPSIS

9        use Math::NumSeq::DigitSum;
10        my $seq = Math::NumSeq::DigitSum->new (radix => 10);
11        my ($i, $value) = $seq->next;
12

DESCRIPTION

14       The sum of digits in each i, so 0,1,...,9,1,2,..., etc.  For example at
15       i=123 the value is 1+2+3=6.
16

FUNCTIONS

18       See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
19       classes.
20
21       "$seq = Math::NumSeq::DigitSum->new ()"
22       "$seq = Math::NumSeq::DigitSum->new (radix => $r, power => $p)"
23           Create and return a new sequence object.  The default is decimal,
24           with no powering, or "radix" and/or "power" parameters can be
25           given.
26
27   Random Access
28       "$value = $seq->ith($i)"
29           Return the sum of the digits of $i, each raised to the given
30           "power" parameter.
31
32       "$bool = $seq->pred($value)"
33           Return true if $value occurs as a sum of digits, which means simply
34           "$value >= 0".
