"The fact that floating-point numbers cannot precisely represent all real numbers, and that floating-point operations cannot precisely represent true arithmetic operations, leads to many surprising situations. This is related to the finite precision with which computers generally represent numbers. For example, the non-representability of 0.1 and 0.01 (in binary) means that the result of attempt… " - Is floating point addition commutative
