Exponential equation with number+exp (expr object)

Hi everybody,

How could I write this equation in expr object: "2 exp (x/64)" ?
I wrote the following argument: " 2exp($f1/64)", but "2exp" is refused. I tried many solutions. Some of them are accepted but there isn't any expression that gives the results numbers I expect.

Thanks for your help,

Laurent.

2*exp()
or 2(exp()) will work.

p.s.: and make sure you do not maybe want /64. instead of /64
;)

I tried yet "2*exp($f1/64)" with the point or not. It's accepted, but the mathematical results are not correct.
And "2(exp($f1/64))" doesn't work...

so what were you trying to do with the "2exp" ? (normally writing things together means multiplication. it just doenst work with strings, it requires a parenthesis)
