“50” represents the cents component of the price. The maximum price for a purchase in the system will be ten dollars. A valid data file will contain the leading zeros for the cents in the prices. For example, an item costing $3.05 will be represented in the file as 3.05 and an ...
# Add leading zeros so that groups can be properly sorted groups <- paste(group, sprintf("%03d", item_id), sep = "-") groups <- factor(groups) new_data_frame( list( level = rep(levels, lengths), x = xs, y = ys, piece = as.integer(groups), group = groups, subgroup = ids...

Where such escapes are used for outputting non-printable (including unassigned) characters, 6 hex digits are used (rather than 8 with leading zeros). For clarity, braces are used, for example \samp{\\U\{0effff\}}. \item The parser now looks for non-ASCII spaces on Solaris (as ...
leading_zeros() as usize - 1) } usize::BITS是usize的位数,num.leading_zeros()是最高一位1之前的0的个数.那么求usize::BITS as usize - num.leading_zeros() as usize - 1就是第一个1以后的位数.那么很容易明白最后求出来的就是小于或等于给定数 num 的最大 2 的幂....
