wcalc binary package in Ubuntu Trusty arm64

 Wcalc is a very capable calculator. It has standard functions
 (sin, asin, and sinh for example, in either radians or degrees),
 many pre-defined constants (pi, e, c, etc.), support for using
 variables, "active" variables, a command history, hex/octal/binary
 input and output, unit conversions, embedded comments, and an
 expandable expression entry field. It evaluates expressions using
 the standard order of operations.
 .
 Wcalc uses intuitive expressions. For example, Wcalc will evaluate:
 5sin 4!-7*2(4%6)^2 to be -221.96631678
