Math::Rational::Approx::ContFrac - Rational number approximation via continued fractions
use Math::Rational::Approx::ContFrac; $x = Math::Rational::Approx::ContFrac->new( x => 1.234871035, n => 10 ); ( $n, $d ) = $x->approx; # continue for an additonal number of steps ( $n, $d ) = $x->approx( 3 );
This module is an object oriented front end to the Math::Rational::Approx::contfrac function
$obj = Math::Rational::ContFrac->new( %attr );
Construct an object which will maintain state for the continued fraction. The following attributes are available:
The number to approximate. It must be positive.
The number of terms to generate. This may be augmented in calls to the approx method.
( $n, $d ) = $obj->approx; ( $n, $d ) = $obj->approx($n);
Calculate the continued fractions and return the associated nominator and denominator. If
$nis not specified, the number of terms generated is that specified in the call to the constructor, plus any terms requested by additional calls to approx with
$nspecifies the number of additional terms to generate beyond what has already been requested.
$x = $obj->x;
The original number to be approximated.
$n = $obj->n;
The number of terms generated.
$arrayref = $obj->terms
Returns an arrayref of the current terms.
The residual of the input number as a Math::BigFloat object. This is not the difference between the input number and the rational approximation.
