(8.D.2.5) ReciprocalFract32
Overview
Computes the reciprocal (1/x)
Discussion
Generates the reciprocal of the input signal on a sample-by-sample basis. $out[n]=\frac{\displaystyle 1}{\displaystyle in[n]}$ Note that the module does not do any input checking and if the input is 0 then the output will be NaN.
Type Definition

{
ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure
INT32 exp; // number of guard bits of the reciprocal output. Default is Q9.23 format.
} ModuleReciprocalFract32Class;
