NAME ^

Math::NumSeq::Odd -- odd integers

SYNOPSIS ^

 use Math::NumSeq::Odd;
 my $seq = Math::NumSeq::Odd->new;
 my ($i, $value) = $seq->next;

DESCRIPTION ^

The odd integers

    1, 3, 5, 7, 9, 11, ...
    starting i=0

FUNCTIONS ^

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

$seq = Math::NumSeq::Odd->new ()

Create and return a new sequence object.

Iterating

$seq->seek_to_i($i)

Move the current sequence position to $i. The next call to next() will return $i and corresponding value.

$seq->seek_to_value($value)

Move the current i so that next() gives $value on the next call, or if $value is an even integer then the next higher even.

Random Access

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

Return 2*$i + 1.

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

Return true if $value is odd.

$i = $seq->value_to_i_ceil($value)
$i = $seq->value_to_i_floor($value)

Return (value-1)/2 rounded up or down to the next integer.

$i = $seq->value_to_i_estimate($value)

Return an estimate of the i corresponding to $value.
