indeed
my suggestion would be:
if a floating point type (with higher precision) is provided it sould be
conformant with iec559 (ieee754)
http://en.wikipedia.org/wiki/IEC_559
http://en.wikipedia.org/wiki/IEEE_754-2008

then i suppose it'll look like

    float64 f1;
    float128 f2;
    float256 f3;  //etc.
