Fixed point vs Floating point number - Stack Overflow

WebMay 5, 2014 · 47. A fixed point number just means that there are a fixed number of digits after the decimal point. A floating point number allows for a varying number of digits after the decimal point. For example, if you have a way of storing numbers that requires exactly four digits after the decimal point, then it is fixed point.
