Butterworth filter using ippsIIRGenLowpass and ippsIIR_Direct

I'm trying to implement a Butterworth filter using ippsIIR_Direct. The only versions of this that I have in my installation of MKL are ippsIIR_Direct_16s and ippsIIR_Direct_16s_I. These take an array of filter coefficients in the parameter pTaps, which uses the data type Ipp16s. The only version of ippsIIRGenLowpass that I have is ippsIIRGenLowpass_64f, which produces filter coefficients using the data type Ipp64f. How can I convert these filter coefficients to the correct data type for use in ippsIIR_Direct?

I'm using Visual C++ in Windows.

These functions are a part of the Intel Integrated Performance Primitives, which has its own forum. I'll have your question moved.
