I am trying to convert a polygon feature class (stored in file gdb) to a raster (using the polygon to raster conversion tool in ArcToolbox)�?�.the field in the polygon feature class which I am using to assign the pixel value has only 5 unique values (12, 0.2, 2.68, 0.6 and 0.16) �??the field data type is float, precision set to 3.
When I convert to raster the pixel values with decimal places convert from 3 digits to 10 digits and the value alters e.g. 2.68 becomes 2.680000067 �?? I need it to be exactly 2.68�?�. I know that the source feature class value is correct because if I change the field properties to display the value with 10 decimal places 2.68 become 2.6800000000.
I have tried various creative ways to end up with a floating point raster with the correct values (e.g. creating a field as integer type and multiplying the value by 100 to remove the decimal, creating raster with pixel values as integer and dividing it by a constant floating point raster with value 100.00) but always end up with the 2.680000067.
Any ideas? Thanks
Lucy.
