NAME

6       Math::NumSeq::DigitLength -- length in digits
7

SYNOPSIS

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

DESCRIPTION

14       The length in digits of integers 0 upwards,
15
16           1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,...
17
18       The default is decimal digits, or the optional "radix" can give another
19       base.  For example ternary
20
21           1,1,1,2,2,...,2,3,...
22
23       Zero is reckoned as a single digit 0 which is length 1.
24

FUNCTIONS

26       See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
27       classes.
28
29       "$seq = Math::NumSeq::DigitLength->new (radix => $r)"
30           Create and return a new sequence object.
31
32   Random Access
33       "$value = $seq->ith($i)"
34           Return length in digits of $i.
35
36       "$bool = $seq->pred($value)"
37           Return true if $value occurs as a digit length.  This means simply
38           "$value >= 1" since lengths are 1 or more.
