The

name

element identifies the algorithm or operation of the function. The low-level algorithm that function implements is a

primitive

. This algorithm often has several

variants

for different data types and implementation variations.

For example, the

CToC

modifier in the

ippsFFTInv_CToC_32fc

function signifies that the inverse fast Fourier transform operates on complex floating point data, performing the complex-to-complex (CToC) transform.
