Error when taking an exponent from a large data set

Hello! I have a 1x3000 data array, I am trying to take an exponent and it gives me an error

xanimal=[300 3004 1002 4000 5000 2010 2000 ...]; 
x1=xanimal/200;
x2=exp(x1);
x3=(2 * sin(x2)) - (3.14/3.4)+104.2;
Ansver=x3 *100+ 25.4
Undefined function 'exp' for input arguments of type 'uint32'.

Error in Untitled (line 11207)
x2=exp(x1);

How can I fix this?

x2 = exp(double(x1));

Thanks helped, but then the question arose, the wrong result shows (shows values ​​more than necessary)

"the wrong result shows..."

As you do not show the "wrong result" or explain anything about them or even show what the right result should be or the code that you are now using, then you force us to guess what you are doing. Guessing is not an effective way to debug code. If you want more help, then you need to show us the exact code that you tried, and also the output that you expect.

"(shows values ​​more than necessary)"

I have no idea what that means. Please explain.

I put the double value x2 one value is counted differently when I insert my data array the readings change a little

xanimal=[300 3004 1002 4000 5000 2010 2000 ...]; 
x1=xanimal/200;
x2 = exp(double(x1));
x3=(2 * sin(x2)) - (3.14/3.4)+104.2;
Ansver=x3 *100+ 25.4

Excuse me! the error was in x1 it gives only one of my value, which is greater than 1 and 2
