Hi,

I understand you are asking for the significance of rounding function in Simulink.

Rounding function is applied to input signal and rounds each element of the input signal to produce the output signal.

Based on the selected rounding function, the input signal is processed to produce output signal with same type and dimensions as input.

Possible values for rounding function are : floor (default), ceil, round or fix.

floor - rounds elements to nearest integer value towards minus infinity.

ceil - rounds elements to nearest integer value towards positive infinity.

fix - rounds elements to nearest integer value towards zero.

round - rounds elements to nearest integer.

If you want to round to 0.1 decimal places in simulink.

For example if i has the number 412.456784 and I need the result to be 412.5.

How would you do this ?

Hi, I just do that trick to round to 0.1 decimal in Simulink :

Original signal ----> 10× gain block ----> Round block ----> Output signal ----> ÷10 gain block

So just multiply your signal by 10 before rounding, then after rounding process, divide it by 10.

Hope that helped.
