NAME
App::MathImage::NumSeq::PlanePathDelta -- sequences of coordinates from PlanePath modules
SYNOPSIS
use App::MathImage::NumSeq::PlanePathDelta;
my $seq = App::MathImage::NumSeq::PlanePathDelta->new (planepath => 'SquareSpiral',
delta_type => 'X');
my ($i, $value) = $seq->next;
DESCRIPTION
This module gives coordinates from a Math::PlanePath
as a sequence. There's various choices of what coordinate to take from the path, such as X, Y, radius, dX, dy, etc.
FUNCTIONS
$seq = App::MathImage::NumSeq::PlanePathDelta->new (key=>value,...)
-
Create and return a new sequence object.
$bool = $seq->pred($value)
-
Return true if
$value
is a happy number, meaning repeated sum of squares of its digits reaches 1.
