  25     Description:        return the absolute value of the argument,
  26                         which should be the magnitude of the argument
  27                         with a positive sign.
  28                         -   if x is NaN, return NaN
  29                         -   if x is -0, result is +0
  30                         -   if x is -Infinity, result is +Infinity
