dear list readers,
with GNU Radio Companion v3.6.3-35-g4435082f compiled via build-gnuradio
using transcendental grc-block gives the following error
---------------8<------------
.....
ValueError: itemsize mismatch: throttle(14):0 using 8,
transcendental(13):0 using 16
---------------8<------------
This showed to me, that the transcendental block uses an unexpexted data
type
In the explanations for the block I found:
---------------8<------------
Possible function names can be found in the cmath library. IO may be
either complex or real, double or single precision.
Possible type strings: float, double, complex_float, complex_double
---------------8<------------
I enclosed a diff, applied the the origirnal, works for me
---------------8<------------

< <name>Complex_double</name>
< <key>complex_double</key>
< <opt>type:complex</opt>

< <opt>type:float</opt>

may be I am wrong; or newer versions have corrected the error or no one
else has tested this function unter GRC...
to clarify that: I enclosed the new gr_transcendental.xml
hopefully this applies to those who did not explore the work around by
themself
