Hi everybody
I want to calculate e^3 using Math.pow
I understand that I can do the following :
Math.pow (2.718,3) where 2.718 is the value of " e"
Is there anyway i can use " e" rather than its value for better accuracy e.g Math.pow( e,3) ?
Thanks and have a great a weekend.

Indeed there is. Check out the documentation for the Math class and you should find it near the top.

. . . and if you go through the whole of the Math class, you find how you can dispense with the value of e altogether.

You can use this e.g:
System.out.println( Math.E+"");

1. How does that help to get e^3?
2. To print the value of Math.E, it's unnecessary to concatenate it to an empty String .
luck, db
There are no new questions, but there may be new answers.

Math.pow(Math.E,3);
is working fine for me.

There is something familiar about that post, but I can't quite put my finger on it
