In the last episode we talked about the data representation of integer, a kind of fixed-point numbers. Today we’re going to learn about floating-point numbers. Floating-point numbers are used to approximate real numbers. Because of the fact that all the stuffs in computers are, eventually,...

unit operable to execute instructions, with the data processing unit being responsive to a format conversion instruction to apply a format conversion operation to a number to perform a conversion between the fixed-point representation of the number and the floating-point representation of the number....
These scalar types are broken down into four basic groups: enumeration types, integer types, floating types, and physical types. Enumeration types Enumeration types are built up from explicitly defined values. This is to say that there is no natural range such as integers which have a fixed ...
For example, a binary representation of a generalized fixed-point number (either signed or unsigned) is shown below: where biis theithbinary digit. wlis the word length in bits. bwl-1is the location of the most significant, or highest, bit (MSB). ...
Dapplies to floating-point and fixed-point types and indicates the number of digits following the decimal point. The maximum possible value is 30, but should be no greater thanM–2. Square brackets (“” and “ A summary of the numeric data types follows. For additional information about pr...
Fixed-Point Numbers Fixed-point numbers represent real numbers by using the encoding scheme: V≈Vapprox=SQ+B. Vis a precise real-world value that you want to approximate with a fixed-point number. Vapproxis the approximate real-world value that results from the fixed-point representation. ...
Dapplies to floating-point and fixed-point types and indicates the number of digits following the decimal point. The maximum possible value is 30, but should be no greater thanM–2. Square brackets (“[” and “]”) indicate optional parts of type definitions. ...
? In the fraction representation, our decimal point is typically fixed, so this is often known as fixed point representation ? We will cover a floating point representation later Signed Integers ? So far we have treated all of our numbers as unsigned (or positive only) – To implement signed...
Conververting from a higher range representation to a lower range representationRound-to-zero is used during conversion to another float format. If the target is an integer or fixed point format, round-to-nearest-even is used, unless the conversion is explicitly documented as using another ...
