+** Source: test1.c

+** Purpose: Checks that _finitef correctly classifies all types

+The IEEE single precision floating point standard looks like this:
+
+ S EEEEEEEE FFFFFFFFFFFFFFFFFFFFFFF
+ 0 1 8 9 31
+
+S is the sign bit. The E bits are the exponent, and the 23 F bits are
+the fraction. These represent a value, V.
+
+If E=255 and F is nonzero, then V=NaN ("Not a number")
+If E=255 and F is zero and S is 1, then V=-Infinity
+If E=255 and F is zero and S is 0, then V=Infinity
+If 0<E<255 then V=(-1)^S * 2^(E-1028) * (1.F) where "1.F" is the binary
+ number created by prefixing F with a leading 1 and a binary point.
+If E=0 and F is nonzero, then V=(-1)^S * 2^(-127) * (0.F) These are
+ "unnormalized" values.
+If E=0 and F is zero and S is 1, then V=-0
+If E=0 and F is zero and S is 0, then V=0
