In-Reply-To: Message from "Kevin B. Hendricks" <kbhend@business.wm.edu> of "Sat, 27 Feb 1999 10:09:39 EST." <v03010d00b2fdb9273872@[209.96.179.170]>
There seems to be some confusion between FLT_MIN and MINFLOAT.
FLT_MIN is the smallest NORMALIZED float = 1.1754943508222875e-38F
MINFLOAT is the smallest float (_EXPBASE ** (FMINEXP - 1)) = 1.40129846432481707e-45
I do not know how the JCK actually is testing this, but the
PowerPC IEEE single-precision floating point can represent both values and
the real minimum depends on what one actually means. float.h FLT_MIN does
not have the same meaning as Java Float_Min.
