Formula node

[Volodymyr]

My problem is that I need to calculate expression
like Y=X^2.4; and X must be not integer like 3.5 or 5.231 for example. When I use formula node It needs X as integer to calculate X^2.4.
How can I avoid it and calculate Y as extend.
Does any other way exist of calculating this expression?

^ - in formula node is bitwise exclusive OR, therefore it need only integer value.

power expression in formula node is **.

Look attached example with 3 ways of this expression.
