Re: [Discuss-gnuradio] UHD source output double precision

[Josh Blum]

There are no double or complex double blocks in gnuradio, so the support 
is not added into grc for such types.

If you make custom blocks with double types, you can set the type to 
byte in grc xml file, and set the vector length to be the number of 
bytes in your type.

Only the the io signature must match, so the length in bytes must be 
identical when connecting, gnuradio does not know anything about the 
data type.

Out of curiosity, why the need for double precision?
