# Define precision of Number to Text in Python

Greetings,
I am attempting to calc a LAT and LONG that is in DD to new fields that are DMS. I have the python below that does the trick however I cannot define the precision of the Seconds. So the return ranges from three to 8 decimal places. I would love to use the calculate geometry feature but I need the conversion to be mathmatic based on the attribute. I am also aware of the "Convert Coordinate Notation???  tool but I would like to avoid the join and output process.

Here is the Python
```def decdeg2dms(dd):
negative = dd < 0
dd = abs(dd)
minutes,seconds =  divmod(dd*3600,60)
degrees,minutes =   divmod(minutes,60)
if negative:
if degrees > 0:
degrees = -degrees
elif minutes > 0:
minutes = -minutes
else:
seconds = -seconds
seconds = round(seconds, 5) #my attempt to define it

dms= str(int(degrees)) + " " + str(int(minutes)) + "' " + str(seconds) + "''"

return (dms)
```

and the Exicution:
`decdeg2dms ( !GlobalLati! )`

As I mentioned before the precision is all over the place, any comments would be appriciated

Thanks and have a wonderful day!
