Astro::Coords::Angle::Hour - Representation of an angle in units of hours
use Astro::Coords::Angle::Hour; $ha = new Astro::Coords::Angle::Hour( "12h30m22.4s", units => 'sex'); $ha = new Astro::Coords::Angle::Hour( 12.53, units => 'hour); $ha = new Astro::Coords::Angle::Hour( 12.53 );
Class similar to
Astro::Coords::Angle but representing the angle as a time. Suitable for use as hour angle or Right Ascension. Inherits from
For hour angle a range of "PI" is suitable, for Right Ascension use "2PI". Default range is none at all. If no units are provided, the units will be guessed using the same scheme as for
Astro::Coords::Angle except that values greater than 2PI will be assumed to be decimal hours.
Return the angle in decimal hours.
$deg = $ang->hours;
As for base class implementation, except that 'hour' (and abbreviation) is a supported format. 'sexagesimal' format will result in a stringified form of the object in hours, minutes and seconds.
$hr = $hour->in_format( 'hour' );
The following methods control the default behaviour of the class.
