Operator '^' cannot be applied to operands of type 'double' and 'double'

[jwr456]

I am using the following:

        var context = new EvalContext() { UseCache = false };
        context.UseCaretForExponent = true;

and getting the following exception

Operator '^' cannot be applied to operands of type 'double' and 'double'

when I try to Eval this

Eval.Execute("someOtherDouble*(1.5^2.0)", this);

and this Operator '^' cannot be applied to operands of type 'double' and 'int'

when I try to Eval this

Eval.Execute("someOtherDouble*(1.5^2)", this);

Can the Eval-Expression.NET not do exponents on doubles or am I doing something incorrectly?

Thanks,

Joel

Never mind, I figured this out:

Eval.Execute("someOtherDouble*Math.Pow(1.5,2)", this);

works

Hello @jwr456 ,

I will re-open it as I believe we have an issue here and your initial code should have worked.

In fact, that's currently working.

The issue is that you create an instance context and specify options to it but you don't use it. You use instead the global context which doesn't have the option and which the ^ operator behaves like the one in C#

Instance Context

var context = new EvalContext() { UseCache = false };
context.UseCaretForExponent = true;
var x1 = context.Execute("3.1*(1.5^2.0)", this);

Global Context

EvalManager.DefaultContext.UseCaretForExponent = true;
var x1 = Eval.Execute("3.1*(1.5^2.0)", this);
