Why won't this code compile??

Every time I attempt to compile this code, I'm receiving a number of errors. Any ideas as to what the problem(s) might be?

Thanks.




public class MyMath
{



public static double exp(double x)
{

double dbloldGuess;
double dblnewGuess = 1 + x;
double dblcounter = 1;

do
{
dblcounter++;
dbloldGuess = dblnewGuess;
dblnewGuess = dbloldGuess + ((x ** dblcounter) / counter);
}
while (Math.abs((newGuess - oldGuess) / newGuess) > 1e-15);

return x;
}
}

What errors?

just look at the variable names. You often forget the dbl prefix.

Yup CornedBee is correct you forgot the
dbl infront of several variable names:

counter, newGuess, Oldguess

and on the line

((x ** dblcounter) / counter);

get rid of one of those *

if you are trying to multiply here:

((x ** dblcounter) / counter);

you only should have 1 *.

Also, avoid putting 'dbl' in front of all double variables because, as you can see, you are confusing yourself. If you need to remember what type of variable 'counter' is then keep it to one letter ( d for double, i for int, b for boolean, and so on... )
