%description
    Fann is a C library implementing multilayer feedforward networks
    with support for both fully connected and sparse connected networks.
    Fann offers support for execution in fixed point arithmetic to allow
    for fast execution on systems with no floating point processor. To
    overcome the problems of integer overflow, the library calculates
    a position of the decimal point after training and guarantees
    that integer overflow can not occur with this decimal point. The
    library is designed to be fast, versatile and easy to use. Several
    benchmarks have been executed to test the performance of the
    library. The results show that the Fann library is significantly
    faster than other libraries on systems without a floating point
    processor, while the performance was comparable to other highly
    optimized libraries on systems with a floating point processor.
