DESCRIPTION

Each of these functions performs data type convert with shifting.

The following equation is used:

dst[i] = src[i] * 2**shift

See the following table for available variations of this group of data type convert functions.

[*] Each row represents a source data type. Each column represents a destination data type.  

PARAMETERS

Each of the functions takes the following arguments:

dst

Destination signal array.

src

Source signal array.

shift

Left shifting factor.

n

Number of samples in the source signal arrays.

 

RETURN VALUES

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
