Title: Casting a DINT as unsigned
Post by: Controls Guy on June 01, 2018, 05:14:26 PM

I'm counting scans and I don't want the counter to roll over negative, but DMD won't let me cast DST0:U, D0:U, etc.

Math stack does not support 32 bit unsigned. It was a trade-off.

This is what I use as a 32-bit counter. Of corse my totalizer is actually 64-bit.
