The Windows calculator has one glaring flaw (and many other minor ones). Even in 'scientific mode' it has no square root button. Sure, sure, you say, you can just take the number to the 1/2-power, that is, to the power of .5, but the square root operand is so common the calculator should have one. It's a real irritant for square root to not have its very own button.
Tangent: meanwhile, I discovered that shift-Insert inserts the value of pi into the calculator. Pretty neat accidental find.

No Square Root Button

click inverse
Click the X^2 button
Square root :D
've often wondered the exact same thing. Lame. You can use some workarounds, of course, like the one in the post or the one josh mentioned, but you shouldn't have to! It's like saying "you can do subtraction - just multiply the second number (or subtrahend) by -1 and then add"
The 'standard view' has a sqrt button... :P
Good call by Bill - use standard mode. You know you don't even know what hyperbolic sine is. Seriously, though - WTF were they thinking?
As Bill said, the Standard view has a sqrt button. The shortcut key for sqrt is @.
The funny thing is when you press @ in Scientific View you get the inverse operation: instead of getting the square root of the number, you get the number squared.
Excuse me, how does taking the inverse and squaring give you x^2?
sqrt(x) = x^(1/2)
sqrt(x) != 1/(x^2) or x^(-2)
And, I totally agree. No sqrt button on scientific mode, what a joke. Now I have to do [input] [x^y] [.] [5] [=]. Tedious.
