Name

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

float d = 200.94, e = 40.2, f = 9.012;
String sd = nf(d, 10, 4);
println(sd);  // prints "0000000200.9400"
String se = nf(e, 5, 3);
println(se);  // prints "00040.200"
String sf = nf(f, 3, 5);
println(sf);  // prints "009.01200"
Description Utility function for formatting numbers into strings. 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.

As shown in the above example, nf() is used to add zeros to the left and/or right of a number. This is typically for aligning a list of numbers. To remove digits from a floating-point number, use the int(), ceil(), floor(), or round() functions.
Syntax 
nf(intValue, digits)
nf(floatValue, left, right)
Parameters
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[]
