Hi,

No, you don't miss any precision.  Internally, the Ruby Float type is
always represented by the C double type, with precision of at least
2.220446049e-16 (depends on how you define it).

You can just try this

    printf "%.6f\n", a

and it will give you your last 6 digits (on display).

Regards,

Bill
