How to write pow to Unit Java (JScience)

Question

I am using JScience API to write units, but I am not able use pow method. How to write pow for unit?

Unit<Length> centimeter = SI.CENTIMETER;
//Unit<Length> cm3 = centimeter.pow(3);eclipse suggests to add cast
Unit<Length> cm3 = (Unit<Length>) centimeter.pow(3);
System.out.println(cm3); // prints cm? instead of cm^3

Sounds like the console can't handle the character for cubed. I'd say your `pow()` call went just fine. — Keppil, Feb 04 '14 at 12:01
I was using mac at the moment, I will try in windows, if it makes any difference. — Vijay Vennapusa, Feb 04 '14 at 12:07

I think it is a UTF-8 3-superscript?

You can check it by analysing the bytes from cm3.toString()

byte[] bs = cm3.toString().getBytes("UTF-8");
for ( byte b : bs )
{
    System.out.println( b );
}

My output (using 3 superscript) of the next string:

byte[] bs = "cm³".getBytes( "UTF-8" ); // byte[] bs = "cm\u00B3".getBytes( "UTF-8" );
for ( byte b : bs )
{
    System.out.println( b );
}

99
109
-62
-77

If the first byte array has the same bytes as the second, the output is correct, but your console cannot display the character ³

System.out.print(bs);// = [B@6f507fb2 – Vijay Vennapusa Feb 04 '14 at 12:06 — Vijay Vennapusa, Feb 04 '14 at 12:06
