You have to know how the operators map to the target language.
For Python, you'd do things like this:

%rename(__add__) SAPrice::operator +(SAPrice const &);
%rename(__iadd__) SAPrice::operator +=(double);
%rename(__sub__) SAPrice::operator -(SAPrice const &);
%rename(__isub__) SAPrice::operator -=(double);
%rename(__neg__) SAPrice::operator -();
%rename(__mul__) SAPrice::operator *(SAPrice const &);
%rename(__imul__) SAPrice::operator *=(double);
%rename(__div__) SAPrice::operator /(SAPrice const &);
%rename(__idiv__) SAPrice::operator /=(double);

%rename(__eq__) SAPrice::operator ==(SAPrice const &);
%rename(__ne__) SAPrice::operator !=(SAPrice const &);
%rename(__lt__) SAPrice::operator <(SAPrice const &);
%rename(__gt__) SAPrice::operator >(SAPrice const &);
%rename(__le__) SAPrice::operator <=(SAPrice const &);
%rename(__ge__) SAPrice::operator >=(SAPrice const &);

%rename(__radd__) operator+(double lhs, SAPrice const & rhs);
%rename(__rsub__) operator-(double lhs, SAPrice const & rhs);
%rename(__rmul__) operator*(double lhs, SAPrice const & rhs);
%rename(__rdiv__) operator/(double lhs, SAPrice const & rhs);
