Angle Units
#Cycles angle-unit setting between
degrees, radians, and grads
without affecting displayed number.
" Q Cycles (converts) angle-unit setting
between degrees, radians, and
grads for display, entry, and
calculation.

" Q RAD 0.785398163
" Q GRAD 50.
" Q DEG 45.
DMS
Enter DMS (Degrees/Minutes/Seconds) values as
D.MMSSs, using 0s as necessary:
Ddegrees (0–7 digits)
.decimal-point separator
MM minutes (must be 2 dig its)
SS seconds (must be 2 digits)
sfractional 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
converts it to decimal.
30.09090 " q 30.1525
" w Temporarily displays current value as
DMS.
