Projects / units-filter


Units-filter is a basic standalone filter written in C, flex, and bison. It inputs strings like "1.5e3 nN.m.s^-1" (which could be the time growth ratio of a torque) and outputs the value in standard SI units, followed by the physical dimension of this value. This parser can be embedded in educational test systems, in order to analyze a student's answer to a problem of physics or chemistry.

      Release Notes: The support for quantities with a particular number of significative digits was added. For example, the entry "1.02m#5" or "1.0200m" are equivalent and signify a distance measurement precise at the sub-millimeter scale. Both would yield the output "1.0200e+00 m".
