## Help needed to display a real number in a readable format

I am trying to diplay a calculation and am having trouble as I dont know

where the decmal place will be... It is a percentile value so always 2 dec

places, but the mantissa could be anything. I get a really long answer at

the moment and was hoping someone knows an easier way to do this..

//cumulative Time = CumTime

//array values = arTime[0,0]

// Calculate total daily hrs from arTime[] (hrs*60 + mins)/60

cumTime := ((arTime[0,1] - arTime[0,0])*60 + (arTime[1,1] -

arTime[1,0]))/60;

strgWkRoster.Cells[y,2] := FloatToStr(cumTime);

I need the answer to be in 00.00 or 0000.00 style

Thanks Tony
