Results

The calculator can display up to 10 digits plus a minus
sign (-9,999,999,999 through 9,999,999,999) and a
2-digit exponent. Results with more than 10 digits
display in scientific notation.

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
