How do I....?

[mik123]

Hi!

I am a beginner using eSignal 7.4.

I have been using the 'Formula Wizard' (or trying to :-) and failing miserable <sigh>

I am trying to create a EFS, part of which is to calculate the Square Root of the 'Open' multiplied by the 'Close'.
Something like SQRT(Open * Close)

How do I calculate a 'Square Root'? - I can't find it anywhere?

Or does it not have a 'Square Root' function?

Detailed help/comments/workaround greatly appreciate.

Thanks

Mik

Hi Mic:

All Javascript math functions need to be preceded by "Math."

So, the square root of the close in EFS would be:

myVar = Math.sqrt( close() );

You can also raise to a power using the Math.pow() function

myVar = Math.pow( close(), 2 );

... give you the square of the close.



Note the case used above... the "M" in Math must be uppercase, the rest lowercase.

For future reference, you can go to the EFS Help Center and Library to look stuff like that up:

I also have standalone versions of the EFS help file available here:

Hi!

I was getting the syntax all wrong. (New and very ignorant of Javascript syntax <sigh>)

This is great!

Thanks very much, Chris
