# NAME

Math::NumSeq::DigitCountHigh -- count of given high digits

# SYNOPSIS

`````` use Math::NumSeq::DigitCountHigh;
my \$seq = Math::NumSeq::DigitCountHigh->new (radix => 10,
digit => 9);
my (\$i, \$value) = \$seq->next;``````

# DESCRIPTION

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.

# FUNCTIONS

See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence 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.

## Random Access

`\$value = \$seq->ith(\$i)`

Return how many of the given `digit` is in `\$i` written in `radix`.

`\$bool = \$seq->pred(\$value)`

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