How can I force MatLab to display integers in function sprintf ?

Hi,
I would like to save graphs in a loop and use sprintf to change the file names, but don't want to have decimal places because this destroys the file extension. The loop is:
for i=1:5
x = [0 ; 0.44; 1.1; -1,1; -0.44];
sprintf('Graph %2d.png',x(i)*100)
end
When I use x(3) =1.1 sprintf('Graph %2d.png',x*100) gets displayed as " Graph 1.100000e+02 ". The same problem does not occur with sprintf('Graph %2d.png',110). If x = 0.44 is also works fine. How can I force MatLab to display integers for every number?
Thanks for your help!!

Due to the limits of floating point arithmetic, 1.1*100 is not precisely represented as 110.
You could try
round(x(i)*100)

I recommend using the '%04i' syntax which will maintain alphabetical order:
sprintf('%03i',6)

Actually sprintf already preforms a round operation internally, so adding an explicit round is unnecessary and just slows it down. If you want to guarantee that the output does not use exponent notation, then %.0f format is best:
>> sprintf('%03.0f',456.9)
ans = 457
Note the rounding!
