bug in cblas_sscal ( ) ?

[Customer__Intel4]

Hi

I discovered that when usingcblas_sscal ( ) to scale an array to zero values, sometimes ( not every time) an entry of the array after scaling becomes nan. The command simply reads:cblas_sscal(L, 0.0, A, 1); where L is the length of the array A.

cblas_sscal() requires a float constant. If you have a correct prototype in scope (by the supplied include files), the compiler would take care of cast from the double value you supplied.

Hi,
If input the data type is no problem, it needs a test code that could show thi problem. Feel free to post here if you have.

Thanks,

If your input array A contains NaNs, then scaling a NaN value with 0.0 will still give a NaN.
