Name

nfs()

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.

Examples

  • 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" 
    String sf = nfs(f, 3, 5); 
    println(sf);  // Prints "-009.01200"
