Hello,

I use a To File Block in my simulation to export data. But there are 15 digits after the point. I don’t need this high accuracy.

How do I set the number of decimal places? In general I don’t need such precise calculations. Is it possible to diminish the precision to improve the simulation speed?

King Regards

There is not a setting to adjust the number of decimal places in the output. PLECS uses double precision floating point numbers which determines the decimal precision of the output.
