NAME

6       Math::NumSeq::DigitLengthCumulative -- total length in digits of
7       numbers 1 to i
8

SYNOPSIS

10        use Math::NumSeq::DigitLengthCumulative;
11        my $seq = Math::NumSeq::DigitLengthCumulative->new (radix => 10);
12        my ($i, $value) = $seq->next;
13

DESCRIPTION

15       The total length of numbers 0 to i, starting from i=0.
16
17           1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20, 22, 24, 26, ...
18
19       "0" is taken to be a single digit, so the initial i=0 is total length
20       1.  Then it's length 1 more for each of i=1 to i=9, then at i=10 length
21       2 more, etc.
22
23       The default is decimal, or the optional "radix" parameter can select
24       another base.  For example "radix => 3" ternary,
25
26           1, 2, 3, 5, 7, 9, 11, 13, 15, 18, 21, 24, 27, 30, ...
27

FUNCTIONS

29       See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
30       classes.
31
32       "$seq = Math::NumSeq::DigitLengthCumulative->new (radix => $r)"
33           Create and return a new sequence object.
34
35   Random Access
36       "$value = $seq->ith($i)"
37           Return total length in digits of the numbers 0 to $i, inclusive.
38
39       "$bool = $seq->pred($value)"
40           Return true if $value occurs in the sequence.
41
42       "$i = $seq->value_to_i_floor($value)"
43           Return the index i of $value or of the next cumulative total below
44           $value.
45
46       "$i = $seq->value_to_i_estimate($value)"
47           Return an estimate of the i corresponding to $value.
