NAME
Math::Rational::Approx::MaxD  approximate a number with a rational number up to a given denominator
SYNOPSIS
use Math::Rational::Approx::MaxD;
# approximate up to denominator of 10
$rat = Math::Rational::Approx::MaxD>new( x => $x, maxD => 10 );
($n, $d ) = $rat>approx;
# approximate up to denominator of 20
($n, $d ) = $rat>approx( 20 );
DESCRIPTION
This module is an object oriented front end to the Math::Rational::Approx::maxd function
INTERFACE
 new

$obj = Math::Rational::Approx::MaxD>new( %attr );
Create a new object. The following attributes are available
x

The number to approximate.
maxD

The limiting maximum denominator to check;
bounds

Optional. A reference to a four element array containing the initial bounds on the region to search. It takes the form
bounds => [ a, b, c, d ]
where the elements are all nonnegative integers and the bounds are given by
a/b < x < c/d
By default it searches from
float(x)
tofloat(x)+1
.
 approx

( $n, $d ) = $obj>approx; ( $n, $d ) = $obj>approx( $maxD );
Return the nominator and denominator for a given maximum value of the denominator. If
$maxD
is not specified it is that specified in the call to the constructor or in any subsequent call to approx. New values of$maxD
less than one already specified are ignored.  bounds

$bounds = $obj>bounds;
Return an arrayref which contains the current bounds on the search, in the same format as the
bounds
attribute passed to new.  x

$x = $obj>x;
The original number to be approximated.
 maxD

The current value of the maximum denominator.
