I am getting a rather unclear type error, and after searching online I cannot find any solutions that help. I am trying to create my own python toolbox for wifi router signal loss, and I am trying to create a raster based on a few inputs that will populate from an equation. The error that I am getting lies on line 107, which is the equation line
fspl= (4 * math.pi * distmod * dist_float * hertz)/(2.99792458 * (10**8))output_rast = fsplI cannot figure out what is causing this error, initially it did not like me trying to use a raster instead of a float, so I changed the distance raster into a float, and now it does not seem to like the float being part of the equation. Here is the rest of my code incase the error stems from an earlier mistake. I cannot find anything that relates to my specific error, and I have not been able to find any way to to work around this issue. Any suggestions?
