How do you do square roots on turing? Im new so...

[UraniumLobster]

Just wanted to know how you use square roots/cube roots in turing. I have to make a calculator which is simple I just don't know/remember how to square root a number. I haven't programmed in over 3 years, and it has slipped my mind...

If I recall correctly, you might want to check out something along the lines of sqrt(). Also remember F10 is your friend.

You could just use exponents

sqrt(x) = x**0.5

[Clayton]

Yes. Remember that x^1/n is the nth root of that number. So 8^1/3 will give you 2 (the cube root of 8)

And on that note, so is F9 unless they changed something.

F9 will give you the page for the keyword your cursor is blinking on, F10 will just open up the help manual.

"number"**"exponent"

On a related note, isn't it messed up that the squared number is inside the brackets uinstead of the number the be squared. It took me a long time to understand that.

[Cervantes]

Uh, Zampano, the square root function takes a number x and returns the number that, when squared, gives x. You might say sqrt(x^2) = x (ie. sqrt and f(x) = x^2 are inverse functions when defined on the positive reals). So it does make sense that the squared number is the parameter to sqrt.
