[Discuss-gnuradio] math range error?

[joe j]

Hi everyone,
    I'm currently working on angle manipulation from "Angle manipulation & other concerns" (earlier postings).  Whenever I use scopesink.py and fftsink.py functions to graph data, I getting math range error - not sure why.  Here's the exact error message I got:
 Traceback (most recent call last):
   File "/root/gr/lib/python2.4/site-packages/gnuradio/wxgui/scopesink.py", line 399, in format_data
     self.Draw (graphics, xAxis=x_range, yAxis=self.y_range)
   File "/root/gr/lib/python2.4/site-packages/gnuradio/wxgui/plot.py", line 879, in Draw
     graphics.scaleAndShift(scale, shift)
   File "/root/gr/lib/python2.4/site-packages/gnuradio/wxgui/plot.py", line 356, in scaleAndShift
     o.scaleAndShift(scale, shift)
   File "/root/gr/lib/python2.4/site-packages/gnuradio/wxgui/plot.py", line 149, in scaleAndShift
     self.scaled =
 scale*self.points+shift
 OverflowError: math range error
 
It seems like there's a bug in my code (or I'm missing something):
         src1 = gr.file_source(gr.sizeof_gr_complex, options.input_first_file, True)
         src2 = gr.file_source(gr.sizeof_gr_complex, options.input_second_file, True)
         dst = gr.file_sink(gr.sizeof_gr_complex, options.output_file)        
 
         c2mag = gr.complex_to_mag()
         f2c = gr.float_to_complex()
                 
         conj = gr.conjugate_cc()
         mult = gr.multiply_cc()
         div =
 gr.divide_cc()
 
         self.connect(src1, (mult, 0))
         self.connect(src2, conj, (mult, 1))
         self.connect(src2, c2mag)
         self.connect(mult, (div, 0))
         self.connect(c2mag, f2c, (div, 1))
         self.connect(div, dst)
 
 Thanks,
 JC
