11 digit => 9);
12 my ($i, $value) = $seq->next;
13
15 The count of how many of a given digit are at the low end of $i when
16 written out in a given radix. The default is to count how many low 9s
17 in decimal. For example i=9599 has value 2 as there's two consecutive
18 9s at the low end.

21 See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
22 classes.
23
24 "$seq = Math::NumSeq::DigitCountLow->new (radix => $r, digit => $d)"
25 Create and return a new sequence object.
26
27 "digit" can be -1 to mean digit radix-1, the highest digit in the
28 radix.

30 Random Access
31 "$value = $seq->ith($i)"
32 Return how many of the given "digit" is in $i written in "radix".
33
34 "$bool = $seq->pred($value)"
35 Return true if $value might occur as a digit count, which means
36 simply "$value>=0".
