Square root

Simple question, is there square root (built-in) in gscript?

x^.5 is the same thing.

Thanks, was hoping for a built-in one tho, but that will work :)

You could create a public function squareRoot( v) return v ^ 0.5;

I thought that sqrt(val) worked as well? Or am I soo 5 years ago or something

Didn't work, but I know that sqrt(float) works in some other script languages like C I think

C isn't a 'script language', and it only works because there is a library that implemented it.

PHP Code:


		
			
#include <math.h>

double sqrt(double);

or something like that.

oh, didn't know that :p Well, thanks guys, I'll now start working on something I needed square root for :)

Massokre's Interesting Fact of the Day:
The ENIAC, a computer that was used in the design of the hydrogen bomb, had a divider/square-rooter built into it's hardware. It could perform 40 divides per second or 3 square roots per second.

Nice, now Stefan can find this computer and connect it too graal? :D
Did you make the bomb? :)

Square root is done by x^0.5, which is actually internally converted into a sqrt() C call for best speed

:O so x^0.5 equal to sqrt(x)? nice

*wants his xor operator back* :-(

I'd even be willing to write the program that would convert everyone's nw files and scripts from

a^b to pow(a,b),
a^=b to a=pow(a,b)
and,
a xor b to a^b

How I use Xor, is this >_>

PHP Code:


		
			
function onCreated() {

 var1 = "foo";

 var2 = "bar";

 echo(var1 xor var2 ? 1 : 0); // would return true

}

/*

   True  = Not alike

   False = Alike

*/

X_x.. Why are you using xor on strings? That's not how it works :x

Might as well be doing be doing "f" xor "b" considering I believe binary operators compare only one binary value (that is, the first binary value per argument)... Not that that piece of code is of any use to anyone (see Okie's post). "f" xor "b" is char(6), whatever that is. char(6) has an ASCII of 6 which is not 0, thus is true...

well, xor works logically, too. I would imagine that that would return false since both strings exist.

Some guy told me to try out xor on strings :p
I have tried it on binary's, but I didn't quite understand it all :)

xor is both a binary operator and a bitwise operator!

boolean xor boolean : one or the other but not both
int xor int : see my bitwise operators tutorial
