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.

Type [*]	F32	F32S
U8	Y
S8	Y
S16	Y
S32	Y
U8S		Y
S8S		Y
S16S		Y
S32S		Y

[*] 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.
