DMNFTF — Exponentiation rule

  • Key: DMNFTF-81
  • Legacy Issue Number: 19232
  • Status: closed  
  • Source: Object Management Group ( Andrew Watson)
  • Summary:

    "Arthmetic exponentiation (grammar rule 4c) is defined as the multiplication of the first operand by itself as many time as indicated by the second operand. It is defined only when the first operand is a number and the second operand is an integer." Given the context, "integer" should presumably read "positive integer". But why the constraint? 1.2**3.6 is perfectly well-defined. Is there a good reason to outlaw it? Also, "Arithmetic" is misspelled.
