DMN14 — Wrong example for 10.6.1 Context Figure 10.18: Example context

  • Key: DMN14-73
  • Status: open  
  • Source: Red Hat ( Matteo Mortari)
  • Summary:

    This is taken from the DMN spec :

    (amount *rate/12) / (1 – (1 + rate/12)**-term)
    

    however this would fail to parse correctly as the first subtraction sign is an "en-dash" (0x2013) and not a minus/hyphen sign (0x2D)

    (amount *rate/12) / (1 – (1 + rate/12)**-term)
                           ^ 
    (amount *rate/12) / (1 - (1 + rate/12)**-term)
    

    this "en-dash" can be confused easily, especially depending on the font used, but as an end result cannot be copy-pasted from the PDF/Word of the DMN specification into an editor, and in essence is a wrong FEEL expression.

    Proposal

    with reference to DMNv1.3 dtc/19-12-06 in chapter Wrong example for 10.6.1 Context Figure 10.18: Example context page 177 replace:

    (amount rate/12) / (1 – (1 + rate/12)*-term)

    with

    (amount rate/12) / (1 - (1 + rate/12)*-term)

    (for the editor, please be aware MS Word might be tempted to replace the minus sign in "1 - ( 1 +" with an en-dash character, but this being FEEL code expression must be a minus sign)
