There are two problems with real numbers on computers.

1. Not every real number have an exact binary representation. For example 0.1 when represented in binary is 0.0001100110011001100110011001100110011001100110011001101 now when you convert it back to real number you will get 0.10000000000000001. Note you can try this calculation by hand and this inaccuracy has got nothing to do with how we represent real numbers in computer.

2. There are uncountably infinite real numbers but computers can only represent and manipulate finite numbers (Well at least in hardware). This means that not every real number can be expressed in computer.

Hope this makes it clear.
