Description Utility function for formatting numbers into strings. Similar to nf() 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 digits, left, and right parameters should always be positive integers.
nfs(intValue, digits)
nfs(floatValue, left, right)
intValue int or int[]: the number(s) to format
digits int: number of digits to pad with zeroes
floatValue float or float[]: the number(s) to format
left int: number of digits to the left of the decimal point
right int: number of digits to the right of the decimal point
Returns String or String[]
