Name

nfp()

Description

Utility function for formatting numbers into strings. Similar to nf() but puts a "+" in front of positive numbers and a "-" in front of negative numbers. 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.

Examples

  • int a=200, b=-40, c=90; 
    String sa = nfp(a, 10); 
    println(sa);  // Prints "+0000000200" 
    String sb = nfp(b, 5); 
    println(sb);  // Prints "-00040" 
    String sc = nfp(c, 3); 
    println(sc);  // Prints "+090" 
     
    float d = -200.94, e = 40.2, f = -9.012; 
    String sd = nfp(d, 10, 4); 
    println(sd);  // Prints "-0000000200.9400" 
    String se = nfp(e, 5, 3); 
    println(se);  // Prints "+00040.200" 
    String sf = nfp(f, 3, 5); 
    println(sf);  // Prints "-009.01200"
