how to set the default datatype of simulink block output to single

how to set the default datatype of simulink block output to single, for example i just want the output datatype of signal builder set to signle, i do not want use data type convert to realize.

According to https://stackoverflow.com/questions/23337769/change-standard-data-type-simulink-matlab-function-block

"It could by possible by changing the parameter "Default for underspecified data type" (DefaultUnderspecifiedDataType) in the Optimization category inside the Configuration Parameters of your model to single.

I'm not sure if it affects MATLAB function blocks, though."

Hi,

I understand that you would like to set the default data type of the Signal Builder block to 'single.'

As of the Simulink R2018b release, the Signal Builder block only supports the 'double' data type. To work around this issue, you can place a Signal Conversion block at the output port of the Signal Builder block and configure its data type to 'single.'

Please refer to the following MATLAB documentation link to know more about Signal Conversion block:
