We're porting the VAX math RTL to an alternative instruction set.
I've been porting G-floating sine and cosine. The problem is that
we're unable to find two numbers that will test the Leading_ones
and Leading_zeros code paths in the VAX MTH$GSINCOS\REDUCE_LARGE
routine.
This probably doesn't mean anything to people not already familiar
with the VAX implementation of g-floating sine and cosine. I believe
I can explain further...but I'll wait a day or two to see if somebody
has some numbers that they've used to test these.
Thanks for your help,
Jeff East

Good timing! Just last week, I wrote software to find the 'closest'
such numbers for H-floating. Modifying the code for G-float is no
problem.
