    int a=200, b=-40, c=90;
    String sa = nfs(a, 10);
    println(sa);  // Prints " 0000000200"
    String sb = nfs(b, 5);
    println(sb);  // Prints "-00040"
    String sc = nfs(c, 3);
    println(sc);  // Prints " 090"

    float d = -200.94, e = 40.2, f = -9.012;
    String sd = nfs(d, 10, 4);
    println(sd);  // Prints "-0000000200.9400"
    String se = nfs(e, 5, 3);
    println(se);  // Prints " 00040.200"

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.
Syntax |
    nfs(num, digits)
    nfs(nums, digits)
    nfs(nums, left, right)
    nfs(num, left, right)
Parameters |
num | float, or int: the number to format
digits | int: number of digits to pad with zeroes
nums | float[], or int[]: the numbers to format
left | int: the number of digits to the left of the decimal point
right | int: the number of digits to the right of the decimal point
Returns | String or String[]
