NAME

Math::NumSeq::SelfLengthCumulative -- cumulative digit length of own values

SYNOPSIS

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

DESCRIPTION

Cumulative digit length of values from the sequence itself,

    1, 2, 3, 4, ... 9, 10, 12, 14, 16, ... 98, 100, 103, 106, ...

Value 9 is 1 digit, so add 1 to give 10. Then 10 is 2 digits so add 2 to give 12, etc.

The default is decimal digits, or optional radix parameter can give another base. For example radix => 2 binary

    1, 2, 4, 7, 10, 14, 18, 23, 28, 33, 39, 45, ...

The effect in all cases is to step by 1s up to 10, then by 2s up to 100, then 3s up to 1000, etc, in whatever radix. This is similar to DigitLengthCumulative, but its lengths are from i whereas here they're from the values.

FUNCTIONS

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

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

$seq = Math::NumSeq::SelfLengthCumulative->new (radix => $r, to_radix => $t)

Create and return a new sequence object.

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

Return true if $value occurs in the sequence.
