In TI-Basic, there's a Fix function to limit the number of displayed decimal places. For example, Fix 2 would display only 2 decimal digits. However, when I try to convert a number to Degree-Minute-Second notation, I sometimes get more than the number of "fixed" decimal digits. For example,

1.12345678901
Float
Disp Ans►DMS
Fix 2
Disp Ans►DMS
Float
Disp Ans
Fix 2
Disp Ans

displays

1°7'24.444"
1°7'24.444"
1.123456789
1.12

The normal decimals act as expected. However, I would expect the second line to display 1°7'24.44. Is this possible? Or would I have to somehow convert it to a string and prune afterwards? (Keep in mind that I want to shorten the decimal because of the display constraints; I want to display text next to it without overlap).

►DMS will display 0 to 3 digits after the decimal point, solely depending on the length of the decimal. The Fix command, set programmatically or through MODE does not affect this.

Storing a number formatted in DMS in a variable will undo the DMS formatting, and it cannot be stored in a string.

My suggestion would be isolating the degrees, minutes, and seconds in separate variables and working with them from there. In this way, they would also all be affected by the Fix command.

  • Do you mean for me to do the math myself and store the results to separate vars (eg. D,M,S)? Because in that case, displaying it would be an issue. – éclairevoyant Apr 22 '13 at 03:30

    A complicated workaround, to be sure. But yes, and then display D° M' S" – dgund Apr 22 '13 at 22:17
