Detailed Description

Fractional operator class.

This class is used for any RT-operator which operates on fractional coordinates. For a full list of methods, see clipper::RTop

Constructor & Destructor Documentation

RTop_frac()

clipper::RTop_frac::RTop_frac ( const String &  strop )

explicit

constructor: from string description

Construct an RT operator from a string description, e.g. 1/2x,z-y+2/3,x '*' is optional for multiplication, commas are compulsory.
