  24     ECMA Section:       9.7  Type Conversion:  ToInt16
  25     Description:        rules for converting an argument to an unsigned
  26                         16 bit integer in the range 0 to 2^16-1.
  27
  28                         this test uses String.prototype.fromCharCode() and
  29                         String.prototype.charCodeAt() to test ToInt16.
  30
  31                         special cases:
  32                             -0          returns 0
  33                             Infinity    returns 0
  34                             -Infinity   returns 0
  35                             0           returns 0
