If I remember correctly, you have 15 significant digits available. You'd better ask to comp.lang.xharbour, though.

The following sample demonstrates that the precision is 15 significant digits:

FUNCTION MAIN()

    LOCAL n

    n = 0.9999999999999999

    ? n

    n = 0.999999999999999

    ? n

    INKEY( 0 )

    RETURN NIL

The result is:

1.0000000000000000
0.999999999999999
