void arm_q31_to_float (q31_t * pSrc,
float32_t * pDst,
uint32_t blockSize 
)
+
+
Parameters
+ + + + +
[in]*pSrcpoints to the Q31 input vector
[out]*pDstpoints to the floating-point output vector
[in]blockSizelength of the input vector
+
+
+
Returns
none.
+
Description:
+

The equation used for the conversion process is:

+
    
+        pDst[n] = (float32_t) pSrc[n] / 2147483648;   0 <= n < blockSize.

Description:
+

The equation used for the conversion process is:
