<ROUNDUP functions>
Round up the value for the function, ROUNDUP (x,0) = x, to the nearest whole number.
Example: ROUNDUP (50.0,0) = 50 / ROUNDUP (50.3,0) = 51
In edge mode, T2 will be set to the values on the right
side of the table when the shutter is set to the values on
the left side of the table.
In width mode, the shutter will be set to the values on the
left side of the table when the trigger width is set to the
values (T2) on the right side of the table. The shutter
setting is ignored in width mode.
