DMS
Enter DMS (Degrees/Minutes/Seconds) values as
D.MMSSs, using 0s as necessary:
D degrees (0–7 digits)
. decimal-point separator
MM minutes (must be 2 dig its)
SS seconds (must be 2 digits)
s fractional part of a second
For example, enter 48 ¡5'3.5" as 48.05035.
Note: Before using a DMS value in a calculation, you
must convert it to decimal with " q.
" q Interprets display as DMS and
" w Temporarily displays current value as
