This is a Julia package that wraps MPFI.
All functions should be available, except mpfi_put_*
and mpfi_urandom
.
Documentation is available at https://mpfijl.readthedocs.org/en/latest/
You will first need to install the MPFI library.
-
On Ubuntu:
sudo apt-get install libmpfi-dev
-
On Mac:
brew install mpfi
Now install the Julia package from within Julia with
julia> Pkg.add("MPFI")
# MPFI uses BigFloats in its internal representation
# For convenience, let's just use 53 bits (as a Float64)
julia> setprecision(53)
53
julia> using MPFI
# The following creates an interval centered on 1.1.
# Since 1.1 isn't exactly representable as a floating-point number,
# the shortest interval that includes it is returned.
julia> x = Interval("1.1")
[1.0999999999999999e+00, 1.1000000000000001e+00] with 53 bits of precision
# It is also possible to create an interval through its endpoints.
julia> y = Interval(1, 2)
[1e+00, 2e+00] with 53 bits of precision
julia> Interval("[1, 2]")
[1e+00, 2e+00] with 53 bits of precision
julia> x + y
[2.0999999999999996e+00, 3.1000000000000001e+00] with 53 bits of precision
Warning: currently the return values and the error handling from MPFI are ignored.
