+
+BH_Util - Utility Functions
+
+
+=head1 SYNTAX
+
+ #include <BH/Math.h>

+ cc prog.c -o prog -lbh
+
+
+=head1 DESCRIPTION
+
+The BH_Util library provides a set of functions for working with numbers in 
+little-endian and big-endian formats, as well as for classifying floating-point 
+values.
+
+
+=head1 API CALLS
+
+
+=head2 BH_ClassifyDouble
+
+ int BH_ClassifyDouble(double value);
+
+Classifies a floating-point value.
+
+This function returns a combination of the following values:
+
+=over
+
+=item B<BH_FP_NORMAL>
+
+The value is normal or subnormal.
+
+=item B<BH_FP_ZERO>
+
+The value is positive or negative zero.
+
+=item B<BH_FP_INFINITE>
+
+The value is positive or negative infinity.
+
+=item B<BH_FP_NAN>
+
+The value is not a number (NaN).
+
+=item B<BH_FP_NEGATIVE>
+
+The value is negative.
