NAME

Math::NumSeq::FractionDigits -- the digits of a fraction p/q

SYNOPSIS

 use Math::NumSeq::FractionDigits;
 my $seq = Math::NumSeq::FractionDigits->new (fraction => '2/11');
 my ($i, $value) = $seq->next;

DESCRIPTION

The sequence of digits which are a given fraction. For example 1/7 in decimal, being 0.14285714...

    1, 4, 2, 8, 5, 7, 1, 4, etc

The digits are always a repeating sequence of length no more than den-1. In fact if you want to cook up a repeating sequence a,b,c,a,b,c,etc then the fraction is abc/999. In a base other than decimal the "9" is radix-1, ie. the highest digit.

FUNCTIONS

See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.

$seq = Math::NumSeq::FractionDigits->new (fraction => $f)

$seq = Math::NumSeq::FractionDigits->new (fraction => $f, radix => $r)

Create and return a new sequence object giving the digits of $f. $f is a string "num/den", or a decimal "xx.yy",

    2/29
    29.125
    1.5/3.25

The default sequence values are decimal digits, or the radix parameter can select another base. (But the fraction parameter is still decimal.)

If the numerator or denominator of the fraction is bigger than fits Perl integer calculations then Math::BigInt is used automatically.
