Hi Mittyri,

❝ x=0.250000

❝ as it should be

:confused:


How nice, then it is also compiler-dependent...
The issue is that 0.05 cannot be represented accurately in a binary brain.
So, the compiler will need to deal with such a fraction and either round it up or round it down. Whatever it does, it can have downstream implications. In my case it implied that my simple naïve decimal logic (0.25 <=0.25) never evaluated to TRUE because it was not tested as such.
The solution could be to add e.g. 1e-8 to the righthand side. Dumb, but that's logic.
Computers suck.
:-D:-D:-D

Pass or fail!
