WebThere are basically two strategies for representing numbers on computers, fixed-point and floating point (integers can be considered a special case of fixed point). There is also the question of signed verses unsigned. In … 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.
