Math::NumSeq::Odd -- odd integers
use Math::NumSeq::Odd; my $seq = Math::NumSeq::Odd->new; my ($i, $value) = $seq->next;
The odd integers
1, 3, 5, 7, 9, 11, ... starting i=0
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
$seq = Math::NumSeq::Odd->new ()
Create and return a new sequence object.
Move the current sequence position to
$i. The next call to
next() will return
$i and corresponding value.
Move the current i so that
$value on the next call, or if
$value is an even integer then the next higher even.
$value = $seq->ith($i)
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
