  42    Template for LiveConnect Tests

  44    File Name:      number-001.js
  45    Description:
  46
  47    When setting the value of a Java field with a JavaScript number or
  48    when passing a JavaScript number to a Java method as an argument,
  49    LiveConnect should be able to convert the number to any one of the
  50    following types:
  51
  52    byte
  53    short
  54    int
  55    long
  56    float
  57    double
  58    char
  59    java.lang.Double
  60
  61    Note that the value of the Java field may not be as precise as the
  62    JavaScript value's number, if for example, you pass a large number to
  63    a short or byte, or a float to integer.
  64
  65    JavaScript numbers cannot be converted to instances of java.lang.Float
  66    or java.lang.Integer.
  67
  68    This test does not cover the cases in which a Java method returns one
  69    of the above primitive Java types.
  70
  71    Currently split up into numerous tests, since rhino live connect fails
  72    to translate numbers into the correct types.
  73
  74    Test for passing JavasScript numbers to static java.lang.Integer methods.
