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.
Iterating
$seq->seek_to_i($i)
-
Move the current sequence position to
$i
. The next call tonext()
will return$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
.
