Another quick software update can be downloaded from here.
This beta includes support for long-time-missing ceiling and floor functions (brackets). These brackets can be selected from popup menu as any other bracket type, or they can be generated by using \ceil and \floor commands… Only the numerical computation for the floor/ceiling functions is supported so that at least graphs can be plotted.
Several bugs are corrected, among them one that was crashing the software (when working with tables – thanks Maximilian), and another other one that was causing GDI resource leakage.
I played a little with optimization settings, but the improvement is minuscule. Still the new beta is few kilobytes shorter than the previous one, making me happy.
