DEG
(
)
DECM
Takes
x
as an angle in the angular mode cur-
rently set and converts it to degrees. Prefix
may be omitted.
GRAD
(
)
DECM
Like
DEG, but converts to gon or grads.
H
DECM
Takes
x
as hours or degrees in the format
hhhh.mmssdd
and converts them into a de-
cimal time or angle.
H.MS
DECM
Takes
x
as decimal hours or degrees and con-
verts them into
hhhh.mmssdd
as in vintage
HPs. For calculations, use H.MS+ or H.MS
–
then or reconvert to decimal values before.
POL
DECM
Assumes
X
and
Y
containing 2D Cartesian
coordinates (
x , y
) of a point and converts them
to the respective polar coordinates (
r ,
) with
the radius

RAD
(
)
DECM
Works like
DEG, but converts to radians.
REC
DECM
Assumes
X
and
Y
containing 2D polar coordi-
nates (
r ,
)
of a point and converts them to the
respective Cartesian coordinates (
x , y
) .
