Just what is the problem?

This is what floating point is for. To a first approximation, it uses scientific notation to easily represent real numbers. There is also fixed point which uses integer math with an implied, fixed decimal point. While there are numbers that can't be perfectly represented, like 1/3 in decimal, if you have enough digits, it usually works out OK.

Then, there is the Microsoft decimal format which AFAIK, is essentially infinite precision. Mainly for working with money.
