G2 X Y I J problem



List:

starting _angle = 230.076884
 ending angle = 129.790270
 radius       = 0.680000
 center(x) = 5.885186
 center(y) = 3.521496


Above  is the data from the *.dxf file. I used
cad2cnc to produce similar code but the lines
below were produced from code written in C and
declaring all variables as double.
The radii agree to 8 places as 0.68000001".

I can find nothing obviously wrong with the code
but emc reports that the starting and ending radii
are different.
Emc version is Mar 2000.

G01 X 5.44878967 Y  3.0000000
G2 X 5.45000001 Y 4.04400300 I 5.88518587 J
3.52149628

Any guidance would be appreciated.

TIA

Dave
