Utility function for formatting numbers into strings. Similar to <b>nf()</b>, but leaves a blank space in front of positive numbers so they align with negative numbers in spite of the minus symbol. There are two versions: one for formatting floats, and one for formatting ints. The values for the <b>digits</b>, <b>left</b>, and <b>right</b> parameters should always be positive integers.
