annotate Small_CPU/Inc/vpm.h @ 863:0c89c6fa949c Evo_2_23 tip

Bugfix empty line in deco plan (VPM only): Floating numbers were used to calculate the target slot for the time entry of a deco stop. The float rounding caused a time to be written into one line above the intended one. In the next step the misplaced time was overwritten by the next shallower stop. To fix the problem the index calculation has been corrected and in addition digit numbers have generally been added to floating point operations to make the floating operation more visible.
