The first routines says:
If B<32, then B=32
If B<64, then B=64
The second one says:
If B < or = 32, then B=32
If B < or = 64, then B=64
If B = 32, then
#1 says B = 64
#2 says B = 32
If B = 32, then
#1 says B = 64
#2 says B = 32
If B = 64, then
#1 says B = nothing
#2 says B = 64
#2 seems more logical if you are rounding, but whatever.
