Math::NumSeq::SevenSegments -- count of segments to display by 7-segment LED
use Math::NumSeq::SevenSegments; my $seq = Math::NumSeq::SevenSegments->new; my ($i, $value) = $seq->next;
This is how many segments are lit to display i in 7-segment LEDs
i = 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ... value = 2, 5, 5, 4, 5, 6, 3, 7, 6, 8, 4, 7, 7, 6, 7, 8, 5 ...
The segments for each digit are
--- --- --- | | | | | | | --- --- --- | | | | | | --- --- --- --- --- --- --- --- | | | | | | | --- --- --- --- | | | | | | | --- --- ---
Sometimes 7 and 9 have "serif" segments
--- --- | | | | --- | | ---
The seven => $integer
and nine => $integer
options give how many segments those digits should be reckoned. Seven can be 3 or 4. Nine can be 5 or 6.
The total is similar to Math::NumSeq::DigitSum, but with digits mapped through a table of segment counts 0->6, 1->2, 2->5, etc.
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
$seq = Math::NumSeq::SevenSegments->new ()
$seq = Math::NumSeq::SevenSegments->new (seven => $int, nine => $int)
Create and return a new sequence object.
$value = $seq->ith($i)
Return the number of segments to display $i
in 7-segment LEDs.
$i = $seq->i_start ()
Return 0, the first term in the sequence being at i=0.
