I am attempting to convert the azimuth field in a shapefile from degrees to radians using the Field Calculator, but after providing the equation, all the attributes in the new field show up as zero. Equation is [azimuth]*(pi/180). I also tried the calculation using the approximate decimal value of pi/180 and got the same result.
Attached are screenshots of the dialogue window and the problem with the zeros in the attribute table.
Is there a way to fix this without having to use Python or R, and if so how?
Any help would be greatly appreciated!
