How I can avoid get math range error in gerAngle2North function in Honeybee

I am trying to run energy simulation using Honeybee.  

When I investigate the error, found that in some surface the angle is -1.23432101234e+308 which is out of range. (at line 6155 in attached image) 

I tried several way to fix this problem using float or round. However, problem was not solved.  

Can anyone know how I can deal with problem?
