The BESTD
w.p format
writes numbers so that the decimal point aligns in groups of values
with similar magnitude. Integers are printed without a decimal point.
Larger values of
p print the
data values with more precision and potentially more shifts in the
decimal point alignment. Smaller values of
p print
the data values with less precision and a greater chance of decimal
point alignment.
The format chooses the
number of decimal places to print for ranges of values, even when
the underlying values can be represented with fewer decimal places.
