DecimalFormat method in macro

[CARL Philippe (LBP)]

Dear all,
Is there an easy way apply something similar to the Java DecimalFormat("#0.000") feature within a macro ?
I thank you very much in advance for your lighting on this.
My best regards,
Philippe

The ImageJ 1.53d61 daily build adds a String.format() macro function, which is the same as the String.format() method in Java.

Here is an example:

  arr = newArray(23.59004,35.7,3.0,9, 0);
  for (i=0; i<arr.length; i++)
     print(String.format(“%.3f", arr[i]));

And here is the output:

   23.590
   35.700
   3.000
   9.000
   0.000
