# NAME

Geo::Functions - Package for standard Geo:: functions.

# SYNOPSIS

```  use Geo::Functions qw{deg_rad deg_dms rad_deg}; #import into namespace

use Geo::Functions;
my \$obj = Geo::Functions->new;

# 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

## deg_dms

Degrees given degrees minutes seconds.

```  my \$deg=deg_dms(39, 29, 17.134);

my \$deg=deg_dms(39, 29, 17.134, 'N');```

`  my \$deg=deg_rad(3.14);`

`  my \$rad=rad_deg(90);`

`  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);`
