An interval consists of two points. Setting the lower point to Not-a-Number would work exactly the same as setting it to -infinity. Same with the higher point and +infinity. It wouldn't make any sense to set the lower point to +infinity, or the higher one to -infinity, so the sign doesn't convey any useful information in that case.
No, because -Inf < finite and finite < Inf will always return true, whereas NaN < finite and finite < NaN will either throw an exception or, if a quiet NaN acting like IEEE 754, return false.
Agreed, see my most recent response to Jeffrey Hellrung. - -- Chad Nelson Oak Circle Software, Inc. * * * -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkuxRjoACgkQp9x9jeZ9/wQZjgCfZC6016hkPd2dHuhvBX3ON7g+ 3uIAoIV4/r40hRgijrT8F/X8RD/dNEK+ =CA3c -----END PGP SIGNATURE-----
