octave-interval-doc binary package in Ubuntu Jammy riscv64

 The interval package for real-valued interval arithmetic allows
 one to evaluate functions over subsets of their domain. All results are
 verified, because interval computations automatically keep track of any
 errors.
 .
 These concepts can be used to handle uncertainties, estimate arithmetic errors
 and produce reliable results. Also it can be applied to computer-assisted
 proofs, constraint programming, and verified computing.
 .
 The implementation is based on interval boundaries represented by binary64
 numbers and is conforming to IEEE Std 1788-2015, IEEE standard for interval
 arithmetic.
 .
 This Octave add-on package is part of the Octave-Forge project.
 .
 This package provides documentation in HTML format for the octave-interval
 package.
