Thinking about doing a LDCad 1.7 version

[N. W. Perry]

Probably best you don't want to fall in the rabbit hole known as the wonderful world of floating point precision

Yeah…my fear is that I switch to 5 decimal places, and now I'm haunted by rounding errors that are .00001 instead of just .001! 

The option only affects writing of files, reading will always use up to 19 decimal points.

The 19 comes from the maximum power of 10 in a 64 bit integer which is used to store the number after the dot before it's converted to double.

So, if I were to switch from say, 3 to 5 places, and I save a new file…then later I decide to go back to 3 places and re-save that file, it would round all the values down? (I suppose I could just try and see what happens.)
