# Parsing error : invalid syntax (line 1) from ArcGIS Raster Calculator?

I have a (Aspect)raster (32bit, floating point,overall 2.9GB) of a landscape and need to devide it with π/180, in order to get the mean aspect later.

My raster calculator (Spatial Analyst --> Map Algebra --> Raster Calculator ) says:

Python-Syntaxfehler: Parsing error : invalid syntax (line 1)

when I click onto it to calculate it.

What does that mean and how can I work with this raser?

"your_raster_file.tif" / (3.14159265 / 180)
