Note that a is most likely not exactly 2, so the question is, do you want to "display" only the integer part or do you want to "drop" the decimal?

To make it clear:
a = 2.00000000001
a =
2.0000
Displaying the integer part ( ans is a char), but a retains the fraction:
sprintf('%.f',a)
ans =
2
Dropping the fraction ( ans is same class as a):
fix(a)
ans =
2

As Oleg says if you want to 'display' the integer part just cast to String with num2Str() function: http://www.mathworks.it/help/techdoc/ref/num2str.html
If you want to drop the decimal part you can use round() function: http://www.mathworks.it/help/techdoc/ref/round.html
