units-filter binary package in Ubuntu Bionic arm64

 Units-filter is a basic standalone filter written in C language,
 flex and bison. It inputs strings like "1.5e3 nN.m.s^-1" (it could
 be the time growth ratio of a torque) and outputs the value in
 standard SI unit, followed by the physical dimension of this value.
 .
  example :~/src$ echo 1.5e3 nN.m.s^-1 | units-filter
  1.5e-06   2   1  -3   0   0   0   0    0    0
 .
                                   2 -3
  which means : 1.5e-06 (SI unit) m .kg.s
 .
 This parser can be embedded in educational test systems, in order to
 analyze a student's answer to a problem of physics or chemistry.
