Surely the issue is not the particular numeric resolution of the numbers but
the idea that the bounding box limits should be integer multiples of the
resolution?
Is that not accomplished more straightforwardly by things like
min <- resol * floor( min(lat)/resol )
max <- resol * ceil( max(lat)/resol )
?
