Compositional Grammar
Linda Bird
  • Document migration to http://snomed.org/scg
  • Feedback
    • numericValue = decimalValue / integerValue
      integerValue = (["-"/"+"] digitNonZero *digit ) / zero 
      decimalValue = integerValue "." 1*digit
    • How to represent -0.5
  • Solution A (which allows "+0" and "-0.00")

    • numericValue = ["-"/"+"] (decimalValue / integerValue)
      integerValue = (digitNonZero *digit ) / zero
      decimalValue = integerValue "." 1*digit

  • Solution B (which does not allow "+0" and "-0.00"

    • numericValue = decimalValue / integerValue
      integerValue = (["-"/"+"] digitNonZero *digit ) / zero
      decimalValue = (integerValue "." 1*digit) / (("-"/"+") zero "." *zero digitNonZero *digit)
