a x 2^(b/1200)

so I write:

expr $f1 * 2 ($f2/1200)

but the max window gives me the error:

expr: missing operation

2

pow

(

$f1

/

1200

)

I’ve tried various combinations of spaces and commas and what not but I tend to get the same error every time, except from when I really mess up and it gives me a different one. Can anyone help me with what the correct syntax is?

]]>[expr $f1*pow(2,($f2/1200))]

]]>
