FFTW can build only one floating point precision (float, double, long double, quad) at once, but they can all be installed simultaneously as the libraries have different names. It is common packages to decide only at run time which precision FFTW they need, and thus FFTW should offer all precisions at once.

FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of
|
|
arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine
|
|
transforms or DCT/DST). We believe that FFTW, which is free software, should become the FFT library of choice for
|
|
most applications.
