MATLAB: How to remove decimal?

MATLABremoving fraction

Hello,,

i wanna know how to remove decimal??

Example a = 2.0000

how to remove zero beside point so it will be a = 2??

please help me

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

Download my FEX submission, which contains many useful rounding functions:

Then you can simply do this:

>> round2sf([12351231,12752309],2,@floor)
ans =
    12000000    12000000

You can use floor function which rounds toward negative infinity.

A = floor(A);
