Webnum2fixpt casts a real-world value represented in floating-point doubles, OrigValue, as a fixed-point number, outValue. Identifies the real-world value to be cast to fixed-point. Designates the desired fixed-point data type of outValue. Indicates the scaling of the output in either Slope or [Slope Bias] format. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/fixpoint/num2fixpt.html

Through elaboration it ends at a model of an all digital and fixed-point phase-locked loop. The final model can serve a starting point for code generation (both ANSI C or synthesizable HDL). The step-wise elaboration of the model illustrates how Simulink ...

WebFixed-Point Numbers. In computer memory, an item of fixed-point data is stored as an integer. To interpret the data as a real-world number, the computer applies a mathematical scaling to the integer. The scaling is fixed, which means it cannot change during execution.
