For instance, you can't > represent 1/3 exactly as a decimal. That's a "rational" number (or alternately, an algebraic number of order 1. Irrational numbers result from algebraic expressions but aren't representable as a ratio (for instance, the square root of 2, or the number phi - both of these are algebraic numbers of order 2). Trancendentals are numbers which can't result from algebraic expressions with whole number coefficients (for instance, pi and e). All transcendentals are irrational, but not all irrationals are transcendental. http://mathworld.wolfram.com/AlgebraicNumber.html http://mathworld.wolfram.com/IrrationalNumber.html http://mathworld.wolfram.com/TranscendentalNumber.html http://mathworld.wolfram.com/GoldenRatio.html --==_Exmh_1143741763_4126P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFELB1DcC3lWbTT17ARAswzAJ0eLe4vSXa/k3wB5DLR55eV61lZ3ACfdw6q We2CWLbLsrQDe8FrNXiY6Xg= =XRVL -----END PGP SIGNATURE----- --==_Exmh_1143741763_4126P-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
