Math::NumSeq::DigitCountHigh -- count of given high digits
use Math::NumSeq::DigitCountHigh; my $seq = Math::NumSeq::DigitCountHigh->new (radix => 10, digit => 9); my ($i, $value) = $seq->next;
The count of how many of a given digit are at the high end of $i when written out in a given radix. The default is to count how many high 9s in decimal. For example i=9599 has value 1 as there's one consecutive 9 at the high end.
$i
See "FUNCTIONS" in Math::NumSeq for the behaviour common to all path classes.
$seq = Math::NumSeq::DigitCountLow->new (radix => $r, digit => $d)
Create and return a new sequence object.
digit can be -1 to mean digit radix-1, the highest digit in the radix.
digit
$value = $seq->ith($i)
Return how many of the given digit is in $i written in radix.
radix
$bool = $seq->pred($value)
Return true if $value might occur as a digit count, which means simply $value>=0.
$value
$value>=0
