Return non-rounded value when assigning variable to index of array

Hi,
I currently have a 1 column array with values inside of it, when i run the following command:
timeZero = Y(timeZero);
timeZero is presently storing an index location in the array ideally when this happens I expect timeZero to be assigned to Y at that index value, which in this case is 2.801396127049.
But instead when I call the variable in the command window it returns the value 2.8014. In my application this value needs to retain its decimal places even during assignment. Is there a way to fix this, or change how I approach this issue?

are you sure this value is rounded and not just displayed as a rounded value?
you can change the display precision using
format long

You're confusing the data itself with how it is displayed. It is probably a double, meaning the value you attempted to assign was rounded (if necessary) to the nearest value it can encode.
If you need arbitrary (decimal) precision you might want to look into vpa.
I expect the double datatype is already providing you the precision you need.
