Get DataType from a Simulink Consant Block (datatype is propagated from the output)

I would like to get the datatype from a Constant block where the datatype is propagated from the output after update.

For example, block A's output is connected to a signal b (double). What is the command to get the datatype from A so it returns "double" and not "Inherit: Inherit from 'Constant value'"?

For anyone that needs this, the site below is useful for a short script that can be modified to find the blocks. It requires the model to be compiled, which is easy to achieve as long as you have set up "mex" in MATLAB.

MATLAB: Is there a way to get all the blocks with specific datatype (eg. boolean / ufix1) in Simulink model after compiling – Math Solves Everything (imathworks.com)

Make sure your model can pass model update (no errors). See example below:

f14;%open the example model
f14([],[],[],'compile');
p=get_param('f14/u','CompiledPortDataTypes')

p = struct with fields:
      Inport: []
     Outport: {'double'}
      Enable: []
     Trigger: []
       State: []
       LConn: []
       RConn: []
    Ifaction: []
       Reset: []
       Event: []

f14([],[],[],'term')
bdclose('f14')
