## Function Documentation

 void arm_q7_to_float ( const q7_t * pSrc, float32_t * pDst, uint32_t blockSize )
Parameters
 [in] pSrc points to the Q7 input vector [out] pDst points to the floating-point output vector [in] blockSize number of samples in each vector
Returns
none
Details
The equation used for the conversion process is:
```     pDst[n] = (float32_t) pSrc[n] / 128;   0 <= n < blockSize.
```
 void arm_q7_to_q15 ( const q7_t * pSrc, q15_t * pDst, uint32_t blockSize )
Parameters
 [in] pSrc points to the Q7 input vector [out] pDst points to the Q15 output vector [in] blockSize number of samples in each vector
Returns
none
Details
The equation used for the conversion process is:
```    pDst[n] = (q15_t) pSrc[n] << 8;   0 <= n < blockSize.
```
 void arm_q7_to_q31 ( const q7_t * pSrc, q31_t * pDst, uint32_t blockSize )
Parameters
 [in] pSrc points to the Q7 input vector [out] pDst points to the Q31 output vector [in] blockSize number of samples in each vector
Returns
none
Details
The equation used for the conversion process is:
```    pDst[n] = (q31_t) pSrc[n] << 24;   0 <= n < blockSize.
```
