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

yxr 
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) .
