Gnuradio supports most primitive datatypes in C++, as well as complex and vector types grouping them together. The types used in the companion app are enumerated in grc/core/Constants.py in the sourcetree.
- Complex
- The Complex data type generates 8 bytes for each complex data item; where the first 4 bytes are for the real number and the next 4 bytes are for the imaginary number. Both the real and the imaginary values are 4-byte floating point numbers.
- Short
- The Short data type generates 4 bytes for each short data item; where the first 2 bytes are for the real number (I) and the next 2 bytes are for the imaginary number (Q).
