# 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.

`\$seq = Math::NumSeq::Odd->new ()`

Create and return a new sequence object.

## Iterating

`\$seq->seek_to_i(\$i)`

Move the current sequence position to `\$i`. The next call to `next()` 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`.
