Subject: [Bug fortran/33197] Fortran 2008: math functions
Date: Fri, 10 Jul 2009 16:17:00 -0000 [thread overview]
Message-ID: <20090710161740.22969.qmail@sourceware.org> (raw)
In-Reply-To: <bug-33197-13404@http.gcc.gnu.org/bugzilla/>
------- Comment #24 from burnus at gcc dot gnu dot org 2009-07-10 16:17 -------
Regarding expressions with Inf with x being finite according to Mathematica 7:
ArcSin (+/-Inf,x) = (0, -/+Inf)
ArcSin (x,+/-Inf) = (0, +/-Inf)
ArcCos (+/-Inf,x) = (0, +/-Inf)
ArcCos (x,+/-Inf) = (0, -/+Inf)
ArcTan (+/-Inf,x) = (+/-Pi/2, 0)
ArcTan (x,+/-Inf) = (+/-Pi/2, 0)
ArcSinh (+/-Inf,x) = (+/-Inf,0)
ArcSinh (x,+/-Inf) = (+/-Inf,0)
ArcSinh (Inf,+/-Inf) = (Inf,0)
ArcSinh (-Inf,+/-Inf) = (-Inf,0)
ArcCosh (+/-Inf,x) = (Inf,0)
ArcCosh (x,+/-Inf) = (Inf,0)
ArcTanh (+/-Inf,x) = (0,-/+Pi/2)
ArcTanh (x,+/-Inf) = (0,-/+Pi/2)
(For ArcSin, ArcCos, ArcTan, ArcCosh and ArcTanh an expression was returned for
(Inf,Inf).)
