[Easycalc-commits] easycalc/mlib mathem.c,1.34,1.35

[Ton v. O. <tvo...@us...>]

Update of /cvsroot/easycalc/easycalc/mlib
In directory sc8-pr-cvs5.sourceforge.net:/tmp/cvs-serv5225/mlib

Modified Files:
	mathem.c 
Log Message:
For polar graphs now the Deg/Rad/Grd setting is respected and used when
tracking graphs and in the graph preferences form.
Internally all computations are (still) done in radians.
Conversion from/to user angle units is done for input/output.
Changed graph preferences form layout to accomodate the angle unit for
polar graphs.
Eliminated duplication between trigmode and trigmodeg.
