Cube Root

[Jay_Smasher]

How do I take a cube root or any root larger than two? I cannot use the power function ie (x^(1/3). Thanks.

The "Power of X" function is in Numeric>>Logarithmic

Why not?

It tells me must have an integer value.

Hi Jay,

maybe I didn't understand your problem, but I had no problems with roots.

Hi,

Use y=x**(1/3); in a formula node, or x**(1/3) in an expresion node.

Regards,

Wiebe.

Hi


You should try e^(1/3*ln(x))

I see the problem. You are using the Expression Node. Look in the help for this:


^ bit exclusive or
** exponentiation

You are asking LabVIEW to do a bit "exclusive or" instead of exponentiation.
