RPF approximation

[bluscape]

When generating an RPF with Mach 3, the col/row values for a specific col/row is not always exactly the same.
This causes Autoleveller to throw an error saying it cannot load the file.

I had to write an app to round the col/row values such that they are all the same and such that Autoleveller can load the file.

Here is an example of the original RPF:

-27.25978,-1.34941,-0.00079
-21.80737,-1.34941,-0.03235
-16.35576,-1.34941,-0.06549
-10.90414,-1.34941,-0.09311
-5.45253,-1.34941,-0.12230
0.00067,-1.34941,-0.14913
5.45229,-1.34941,-0.17675
10.90548,-1.34941,-0.19963
16.35710,-1.34941,-0.23277
21.81030,-1.34941,-0.26670
27.26270,-1.34941,-0.30142
27.26270,4.39007,-0.25171
21.81030,4.39007,-0.22330
16.35947,4.39007,-0.19490
10.90707,4.39007,-0.17123
5.45466,4.39007,-0.14913
0.00225,4.39007,-0.12704

I've rounded the zero values on lines 6 and 17 such that autoleveller will accept the file.

-27.26,-1.35,-0.00079
-21.81,-1.35,-0.03235
-16.36,-1.35,-0.06549
-10.90,-1.35,-0.09311
-5.45,-1.35,-0.12230
0.00,-1.35,-0.14913
5.45,-1.35,-0.17675
10.91,-1.35,-0.19963
16.36,-1.35,-0.23277
21.81,-1.35,-0.26670
27.26,-1.35,-0.30142
27.26,4.39,-0.25171
21.81,4.39,-0.22330
16.36,4.39,-0.19490
10.91,4.39,-0.17123
5.45,4.39,-0.14913
0.00,4.39,-0.12704

Maybe I'm doing something wrong and need to change the precision in Mach 3?

Thanks
