Helper.buildZeroPrefixAndTruncTrailZeros介绍

[英]Build a numerical string with leading 0s and truncate trailing zeros. number is an existing number that the new string will be built on. totalDigits is the number of the required digits of the string.
[中]构建一个前导为0的数字字符串，并截断尾随的零。number是新字符串将基于的现有编号。totalDigits是字符串所需的位数。
