  \fn bool QJSNumberCoercion::isArrayIndex(double d)
  \internal
 
  Checks whether \a d contains a value that can serve as an index into an array.
  For that, \a d must be a non-negative value representable as an unsigned 32bit int.

  Checks whether \a i contains a value that can serve as an index into an array.
  For that, \a d must be a non-negative value representable as an unsigned 32bit int.

/*!
  \fn int QJSNumberCoercion::toInteger(double d)
  \internal
 
  Coerces the given \a d to a 32bit integer by JavaScript rules and returns
  the result.
 */
 
/*!
  \fn bool equals(double lhs, double rhs)
  \internal
 
  Compares \a lhs and \a rhs bit by bit without causing a compile warning.
  Returns the \c true if they are equal, or \c false if not.
 */
 
/*!
  \fn double QJSNumberCoercion::roundTowards0(double d)
  \internal
 
  Rounds \a d towards 0 by JavaScript \e ToInteger rules and returns the result.
