00005  * $Log: math_constants.h,v $
00006  * Revision 1.1  2000/08/08 23:40:25  laue
00007  * New check-in. Needed only for standalone version
00008  *
00009  * Revision 1.4  2000/01/07 20:15:31  fisyak
00010  * fix linux warnigns
00011  *
00012  * Revision 1.3  1999/12/23 23:21:22  fisyak
00013  * remove egcs warning
00014  *
00015  * Revision 1.2  1998/11/30 16:06:10  fisyak
00016  * Protection versus usage in FORTRAN
00017  *
00018  * Revision 1.1  1998/02/19 15:56:21  fisyak
00019  * Math. Phys. constants from H.Ward
00020  *   
00021  * 
00022  * Most of these were copied from math.h.  The AIX math.h was
00023  * different than the other three, so I am simply going to have
00024  * our own version.
00025  *
00026  * Underscores here often mean 'divided by'.  E.g., PI_2 means pi/2.
