It may depend on how you call your macro.

You can call it this way:
#declare Var= randsign();

Or edit the macro this way:
#macro randsign()
  #if (rand(HPlanet_Seed_Value) > 0.5)
   1;
  #else
   -1;
  #end
#end

and sue it this way:
#declare Val= randsign()

OR, use it in some calculation:

#declare Val= randsign()* Value;
