Fixed point e floating point
WebWarning: Floating point is inaccurate - you can not represent every number as a float e.g. 1/3 can not be represented accurately by a floating point representation since it is a recurring number. Rounding errors creep in which is why you have to use larger and larger floating point representations to get an accurate result.
