# the IRIX is very picky about static functions they must be declared
# as static functions before being used otherwise it will use the 
# nonstatic one or have an unresolved symbol.

# The following appeared on the network on changing quiet NaNs to 
# signaling NaNs:
#        To do this on the SGI, you need to set the environment and load the
#floating point library.  When you are through, reset the environment.  The 
#following example will work quite nicely.  Refer to the man page for fpe for
#details.
#
##
## Trap floating pointing errors for overflows, invalid operations, and
##   divide by zero.  All underflows will be ignored and set to 0.0.
##
##      Overflow - set to NaN to avoid multiple overflows
