# NAME Geo::Functions - Package for standard Geo:: functions. # SYNOPSIS use Geo::Functions qw{deg_rad deg_dms rad_deg}; #import into namespace print "Degrees: ", deg_rad(3.14/4), "\n"; use Geo::Functions; my $obj = Geo::Functions->new; print "Degrees: ", $obj->deg_rad(3.14/2), "\n"; # DESCRIPTION # CONVENTIONS Function naming convention is "format of the return" underscore "format of the parameters." For example, you can read the deg\_rad function as "degrees given radians" or "degrees from radians". # CONSTRUCTOR ## new The new() constructor my $obj = Geo::Functions->new(); # METHODS ## initialize ## deg\_dms Degrees given degrees minutes seconds. my $deg = deg_dms(39, 29, 17.134); my $deg = deg_dms(39, 29, 17.134, 'N'); ## deg\_rad Degrees given radians. my $deg = deg_rad(3.14); ## rad\_deg Radians given degrees. my $rad = rad_deg(90); ## rad\_dms Radians given degrees minutes seconds. my $rad = rad_dms(45 30 20.0); ## round Round to the nearest integer. This formula rounds toward +/- infinity. my $int = round(42.2); ## dms\_deg Degrees minutes seconds given degrees. my ($d, $m, $s, $sign) = dms_deg($degrees, qw{N S}); my ($d, $m, $s, $sign) = dms_deg($degrees, qw{E W}); ## dm\_deg Degrees minutes given degrees. my ($d, $m, $sign) = dm_deg($degrees, qw{N S}); my ($d, $m, $sign) = dm_deg($degrees, qw{E W}); ## mps\_knots meters per second given knots my $mps = mps_knots(50.0); ## knots\_mps knots given meters per second my $knots = knots_mps(25.0); # BUGS Please log on GitHub # LIMITS # AUTHOR Michael R.
