How to Reduce precision in symbolic calculations? I am finding y coordinates of a function using the given values of x, but i need a precision of only 6 digits whereas it is showing precision of upto 32 digits. Is there any way to reduce this.

I have written this code

F(x)=str2sym(input('\n Enter your Function \n','s'));
n=5;
for i=1:n 
       Xc(n-i+1)=cos((2*i-1)*pi/(2*n));
       Yc(n-i+1)=F(Xc(n+1-i));
end

Output for Yc i am getting like this
