    <pre>
x = new BigDecimal("1.0")
y = new BigDecimal("1.1000")
z = x.add(y)                      // 2.1000   
    
x = new BigDecimal("1.20")
y = new BigDecimal("3.45000")
z = x.multiply(y)                 // 4.1400000</pre>

      To specify the precision of a value is to specify that the value lies
      within a certain range.

      In the first example, <code>x</code> has a value of 1.0. The trailing zero
      shows t
