The ►DMS Command

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

The ►DMS command can be used when displaying a real number on the home screen, or with the Disp and Pause commands. It will then format the number as an angle with degree, minute, and second parts.

30►DMS
    30°0'0"
100/9°►DMS
    11°6'40"

It will also work when displaying a number by putting it on the last line of a program by itself. It does not work with Output(, Text(, or any other more complicated display commands.

Although ►DMS is meant as a way to format angles in Degree mode, it doesn't depend on the angle mode chosen, only on the number itself. Note that entering a number as degree°minute'second" will also work, in any mode, and it will not be converted to radians in Radian mode.

Rounding to Nearest Second

If you'd prefer to not have seconds with decimal places, you can round your answer to the nearest second with the following formula:

round(Ans*3600,0)/3600►DMS

Or a slightly shorter version:

round(Ans36,2)/36►DMS

Tip: If you find yourself needing this formula regularly, put it into a Y= graphing-function as:

Y1=round(X36,2)/36

And then you can call it from your home screen via:

Y1(123.45678►DMS

Error Conditions

• ERR:SYNTAX is thrown if the command is used somewhere other than the allowed display commands.
• ERR:DATA TYPE is thrown if the value is complex, or if given a list or matrix as argument.
