In fixed point notation, there are a fixed number of digits after the decimal point, whereas … WebA floating-point (FP) number is a kind of fraction where the radix point is allowed to move. If the radix point is fixed, then those fractional numbers are called fixed-point numbers. The best example of fixed-point numbers are those represented in commerce, finance while that of floating-point is the scientific constants and values.
