Date and Time
Here we will use a unit of time that I named reference day.
This is equivalent to the Julian day with some offset.
A monthly calendar between 1900 and 2100 can be generated
using this reference day.
Time graphs with automatic scale selection are shown as the
application of the reference day.
Special Functions
I included the error function and the Bessel functions as
I found them in <math.h> of the glibc.
I used to use these functions in calculating the satellite communication
quality.
GCS Logo
I tried to design a GCS logo.
This is an example of drawing shapes in the GCS way.
