I found if a floating value is assigned to a variable, sometimes the value will experince a small abount change, as seen below. Why is it like that?

Floating point numbers are represented in computer in a binary base i.e. in base 2. Most of the times the floating point numbers one enters are exactly not represented in binary and they are approximated to the closest values. You need to read about IEEE 754 floating point number representation to know more. You may read the below link to have some idea.
