I am new to Matlab. I noticed a difference when using the ceil function:
a = ceil(511*5e-6*8e5);
b = ceil(511*5*0.8);
May I know the reason why I got different results for a and b?

Hi Silvester,
The results for a and b are different because the expressions for each of them are different. The issue is not with MATLAB but it is due to how the data for floating point numbers are stored in a computer.
For a better understanding please refer to this MATLAB Answer,
I hope this helps you.
