Decimals in the computer, there are two manifestations of fixed-point and floating-point numbers. In the fixed-point machine, because of the location of the decimal point is fixed, as when dealing with a number of machines is not pure decimal or pure integer, the ratio must be multiplied by a factor, otherwise will have a spillover. In fact a number of computer processing is not necessarily the pure decimal or pure integer, and some of the numerical range of data varied widely, not directly with fixed-point or fixed-point decimal integer that must be expressed in floating-point numbers. Floating-point precision than that of fixed-point higher. Asked to use fixed-point calculations to simulate floating-point operations with fixed-point computation to realize the idea of floating point arithmetic.
