NAME

6       Math::NumSeq::Cubes -- cubes i**3
7

SYNOPSIS

9        use Math::NumSeq::Cubes;
10        my $seq = Math::NumSeq::Cubes->new;
11        my ($i, $value) = $seq->next;
12

DESCRIPTION

14       The sequence of cubes i**3,
15
16           0, 1, 8, 27, 64, 125, ...
17

FUNCTIONS

19       See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence
20       classes.
21
22       "$seq = Math::NumSeq::Cubes->new ()"
23           Create and return a new sequence object.
24
25   Iterating
26       "($i, $value) = $seq->next()"
27           Return the next index and value in the sequence.
28
29           If $value overflows a usual Perl UV integer the return is promoted
30           to "Math::BigInt" to preserve all bits.
31
32       "$seq->seek_to_i($i)"
33           Move the current sequence position to $i.  The next call to
34           "next()" will return $i and corresponding value.
35
36       "$seq->seek_to_value($value)"
37           Move the current sequence position so that "next()" will give
38           $value on the next call, or if $value is not a cube then the next
39           cube above $value.
40
41   Random Access
42       "$value = $seq->ith($i)"
43           Return "$i*$i*$i".
44
45       "$bool = $seq->pred($value)"
46           Return true if $value is a cube.
47
48       "$i = $seq->value_to_i_ceil($value)"
49       "$i = $seq->value_to_i_floor($value)"
50           Return the cube root of $value, rounded up or down to the next
51           integer.
52
53       "$i = $seq->value_to_i_estimate($value)"
54           Return an estimate of the i corresponding to $value.
