Convert an angle given in decimal degrees to {degree,minute,second}:

Convert from a string:

This canonicalizes a DMS list:

Return the DMS lists of latitude and longitude of a GeoPosition object:

DMS list form of an angle given in decimal degrees:

For exact inputs, the result is also a list of exact quantities:

A negative angle:

DMS list of an angle given as a DMS string:

The input can be given in multiple forms:

In this input, "23o" means 23 degrees and "11 MOA" means 11 minutes of arc:

Signs in a DMS string can be specified using "North", "West", etc. or abbreviations like "N", "W", etc.:

The sign of the angle can also be explicit in the string, and it applies to all elements:

Canonical DMS list input is returned without change:

Degrees and minutes are always returned as exact numbers:

Canonicalize to a unique form:

An incomplete specification of a DMS string assumes zeros:

Return the array of pairs of DMS lists for the locations in a GeoPosition array:

Act on both angles of a double DMS string:

The angles are returned in {lat,lon} form even if provided in reverse order:

Specify explicitly the meaning of each angle:

Convert a Quantity angle into a DMS list:

For a positive angle θ, DMSList[θ] returns a list of non-negative numbers:

For a negative angle θ, DMSList[θ] returns a list of non-positive numbers:

All numeric angles θ obey the identity DMSList[-θ]-DMSList[θ]:

DMSList does not implement 360-degree periodicity:

If the input contains an inexact number, the result will be inexact, always in the seconds:

Only when all numbers are exact will the result be exact:

The action of DMSList on a numeric angle can be inverted with FromDMS:

With an exact number:

The action of DMSList on a DMS string angle can be inverted with DMSString:

With an exact number:

DMS lists of numeric angles can also be computed with NumberDecompose:

DMSList and NumberDecompose follow the same sign conventions:

DMS lists are equivalent to Quantity objects with degree-minute-second mixed units:

DMSList can extract the DMS list from the Quantity object:

The list can be used as mixed magnitude for the quantity:

There must always be numbers accompanying the units:

Rational numbers should not be used:
