Hi,

I am working with pressure and temprature sensor values in a Simulink project where I need to have higher precision than the one I am getting now which is just only two decimal points. How can I increase precision of the output from basic Math operations such as +-%* blocks. I keep getting two decimal points even if I change the output data type of the blocks to double.

Thanks in advance for the help.

I am using the Simulink env't as I am working in an event driven control system. It would be so nice to know any solution to solve this problem.

You are probably getting more than 2 decimal places of "accuracy". You're probably getting 15 or 16 significant figures worth of accuracy, but only displaying 2 decimal places...
