  Quantifier

  The production QuantifierPrefix :: { DecimalDigits } evaluates as follows:

  1. Let i be the MV of DecimalDigits (see 11.8.3).
  2. Return the two results i and i.

  The production QuantifierPrefix :: { DecimalDigits, } evaluates as follows:

  1. Let i be the MV of DecimalDigits.
  2. Return the two results i and ∞.

  The production QuantifierPrefix :: { DecimalDigits, DecimalDigits } evaluates as follows:

  1. Let i be the MV of the first DecimalDigits.
  2. Let j be the MV of the second DecimalDigits.
  3. Return the two results i and j.
