How can the number of digits found in computed values of exponents be controlled? Here is my problem: I am appling a power fit to statistical data using the following command power:=PowerFit(X,Y,x); and I get the following output: 4.686027976 x^(0.413637849985206863) I would like to have these coefficients truncated to say 3 digits so that the expression is manageable when I insert the expression into a plot title. I have tried: power:=evalf[3](PowerFit(X,Y,x)); which produces 4.69 x^(0.413637849985206863) but I also what the value of the exponent truncated. I have also used the Digits:=3 command, but that produced the same result. Any ideas? Thanks, Phil
