Constructor & Destructor Documentation

UnitAlgebra::UnitAlgebra

(

std::string

val

)

Create a new UnitAlgebra instance, and pre-populate with a parsed value.

Parameters:

val

Value to parse. It is of the following format: val := NUMBER( )?UNITS NUMBER := (-)?[0-9]+(.[0-9]+)? UNITS := UNITGROUP(/UNITGROUP) UNITGROUP := UNIT(-UNIT)* UNIT := (SIPREFIX)?(BASEUNIT|COMPUNIT) SIPREFIX := {a,f,p,n,u,m,[kKMGTPE]i?} BASEUNIT := {s,B,b,events} COMPUNIT := {Hz,hz,Bps,bps,event}
