|FwStatus||fws10Log10_32s_Sfs||(||const Fw32s * pSrc, Fw32s * pDst, int len, int scaleFactor );|
|FwStatus||fws10Log10_32s_ISfs||(||Fw32s * pSrcDst, int len, int scaleFactor );|
|len||Specifies the number of elements in a buffer.|
|pDst||Pointer to a destination buffer.|
|pSrc||Pointer to a source buffer.|
|pSrcDst||Pointer to a buffer that is both the source and destination.|
|scaleFactor||Specifies an integer scaling factor for the Sfs operation. The returned result is multiplied by 2^(-scaleFactor).|
These functions step through vector elements in a source buffer and calculate ten times the common logarithm of each element.
The results are integer scaled, then written to a destination buffer.
This function is particularly useful for calculating logarithmic scale values, such as decibels.
