Hey all,

I looked up Wikipedia's post of the Classpad before I bought it and it described a bug I didn't see here, here it is:

There are however a number of issues with OS 3.03.
For example:
The Definite integral of H(0.9 - x) where H(x) is the Heaviside Step Function and 0<x<1 is 0.9;
OS 3.03 result : -0.9 ( Incorrect )
OS 3.02 result : 0.9 ( Correct )

This can affect many of the calculations in which you get H(x) as a result and can make the calculator to return wrong results in many occasions.

I have emailed this to Casio just to let you know! :greengrin: I'll post with any info. re. this bug.
