%description
fplll contains implementations of several lattice algorithms. The
implementation relies on floating-point orthogonalization, and LLL is central
to the code, hence the name.
It includes implementations of floating-point LLL reduction algorithms,
offering different speed/guarantees ratios. It contains a 'wrapper' choosing
the estimated best sequence of variants in order to provide a guaranteed output
as fast as possible. In the case of the wrapper, the succession of variants is
oblivious to the user.
It includes an implementation of the BKZ reduction algorithm, including the
BKZ-2.0 improvements (extreme enumeration pruning, pre-processing of blocks,
early termination). Additionally, Slide reduction and self dual BKZ are
supported.
It also includes a floating-point implementation of the Kannan-Fincke-Pohst
algorithm that finds a shortest non-zero lattice vector. Finally, it contains a
variant of the enumeration algorithm that computes a lattice vector closest to
a given vector belonging to the real span of the lattice.

%description devel
The libfplll-devel package contains libraries and header files for
developing applications that use libfplll.
# The static library is required by Macaulay2. See its spec file for a full
# explanation; the essential justification is excerpted below:
#
# We have to use the static version of the libfplll and givaro library. They
# have global objects whose constructors run before GC is initialized. If we
# allow the shared libraries to be unloaded, which happens as a normal part
# of Macaulay2's functioning, then GC tries to free objects it did not
# allocate, which leads to a segfault.
