http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/fixpoint/c3_type6.html WebFixed-Point Designer supports general binary point scaling V = Q 2E, where V is the real-world value, Q is the stored integer value, and the fixed exponent E is equal to the negative of the fraction length. In other words, RealWorldValue = StoredInteger 2−FractionLength. The fraction length defines the scaling of the stored integer value.

Webnumerictype object properties define the data type and scaling attributes of a fixed-point object. All properties of a numerictype object are writable. However, the numerictype properties of a fi object become read only after the fi object has been created. WebTo assign a fixed-point data type to a number or variable in MATLAB, use the fi (Fixed-Point Designer) constructor. The resulting fixed-point value is called a fi object. For example, the following creates fi objects a and b with attributes shown in the display, all of which we can specify when the variables are constructed. WebCreate fi object from fi object. When the input value is a fi object, the output uses the same word length, fraction length, and signedness as the input fi object. v = fi (pi,1,24,12); a = fi (v) a = 3.1416 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 24 FractionLength: 12. immigration lawyers birmingham uk
