  • DDN Discussion • Re: Is DCAL single or double precision ? June 26, 2017
    Your assumption is correct, DCAL for Delphi is double-precision. You could even use the Extended data type (10-byte real) in your local computations. Although, any data stored (and used) by DataCAD would revert back to a Double (8-byte real).Statistics: Posted by David A. Giesselman — Mon Jun 26, 2017 3:09 pm

    Thanks Dave,I pretty much assumed that, although the notes about 'existing macros' using single precision does seem to imply otherwise. But it is good to have it confirmed.It is probably obvious why I was wanting to set z-base using DCAL for Delphi (as I assume that will be double precision).Statistics: Posted by dhs — Mon […]

  • DDN Discussion • Re: Locked Layers June 25, 2017
    Am I just to assume that this is a known bug with DataCAD?I no longer have the test drawing where this was occurring and cannot reproduce the problem at this stage. Out of interest, it was not just the DCAL macro that had problems with the entitites on the locked layer .... I could not […]

  • DDN Discussion • Is DCAL single or double precision ? June 25, 2017
    Hi,The release notes from DataCAD 11 state that 'Existing DCAL macros should be compatible with DataCAD 11. Due to DCAL’s limitations, existing macros still use single-precision math.' The implication seems to be that new macros compiled with DataCAD 11 onwards will use double precision.Can anybody confirm what precision DCAL uses? The reason for my question […]

  • DDN Discussion • Workaround for DCAL Real bug June 25, 2017
    Hi,I came across a bug in the DCAL compiler when trying to hard-code a large real value: I was assigning a value of 189999.1 to a real variable, but the resulting value of the variable was -6608.9 !I spent quite a lot of time trying to understand what was going on before I realised what […]
