# Geo::Functions(3pm)

Package for standard Geo:: functions.

## 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

Package for standard Geo:: functions.

## 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);
```
