libqalculate-dev 4.2.0-1 (riscv64 binary) in ubuntu kinetic

 Qalculate! is small and simple to use but with much power and versatility
 underneath. Features include customizable functions, units, arbitrary
 precision, plotting, and a graphical interface that uses a one-line
 fault-tolerant expression entry (although it supports optional traditional
 buttons).

 This package contains the development files needed to build the frontends.
