Numbers that can be calculated by a CPU

Most CPUs can handle the two types, namely fixed-point and floating-point. The fixed-point values have a specific digit on one point desimalnya. This is the limit value that may reach to the numbers, but this can be precisely calculated by the CPU faster. Meanwhile, the number is a floating-point number expressed in scientific notation, where a number represented as a decimal number is multiplied by the rank of 10 (such as 3.14 x 1057). Scientific notation like this is a short way to express the number of very large or very small numbers, and also allow a range of values is very much before and after the point desimalnya. Numbers are generally used in the graph represents and scientific work, but the arithmetic of the number of floating-point is far more complex and can be completed in a long time by the CPU as they may be able to use some CPU cycles tap. Some processors use a computer to calculate its own floating-point number which is called the FPU (also called math co-processor) that can work in parallel with the CPU speed calculation for floating-point number. FPU at this time to become standard in many computers because most of the applications currently operate using many floating-point number.
