[Paraview] PV 4.1.0: save the data saves only 1/2 of a circle PROBLEM SOLVED - SAVE the csv file using the SCIENTIFIC NOTATION

[Stephen Wornom]

Recall that I have two cylinders.

1- extract a surface
2- connectivity
3- threshold 
4  slice in the z-coordinate

This produces two circles in the x-y plane. 
5- I save the data in a csv file using the default format.
6- To read the cvs file in fortran, I replace the commas by a blank.
7- I read the csv file in a fortran program and plot the values for y> 0 (upper circle) and y<0 (lower circle)
8 Result is upper circle points ar missing.

Cause is csv file was written with the default notation which has reals and integers which I then read as reals in the fortran code.
