    If this is in Java, check out the NumberFormat class's setMinimumFractionDigits() method.

    Example:

    double d1 = 2.5;

    nf.setMinimumFractionDigits(2);
    
    String d1s = nf.format(d1);
    String d2s = nf.format(d2);
    
    System.out.println("d1s: " + d1s + " and d2s: " + d2s);
    

    produces

    d1s: 2.50 and d2s: 5.00
