NAME
Math::NumSeq::DigitCount  count of a given digit
SYNOPSIS
use Math::NumSeq::DigitCount;
my $seq = Math::NumSeq::DigitCount>new (radix => 10,
digit => 9);
my ($i, $value) = $seq>next;
DESCRIPTION
The count of how many of a given digit is in $i
when written out in a given radix. The default is to count how many 9s in decimal.
FUNCTIONS
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
$seq = Math::NumSeq::DigitCount>new (radix => $r, digit => $d)

Create and return a new sequence object.
digit
can be 1 to mean digit radix1, the highest digit in the radix.
Random Access
$value = $seq>ith($i)

Return how many of the given
digit
is in$i
written inradix
. $bool = $seq>pred($value)

Return true if
$value
might occur as a digit count, which means simply$value>=0
.
