 Arbitrary Precision Arithmetic (APA) package for Octave/Matlab. This package
 is a wrapper around the MPFR library, which provides arbitrary precision

 with a precision that can be set at runtime, making it suitable for
 applications that require high precision, such as numerical analysis and
 scientific computing.
