The ^ is actually a bitwise XOR operator. You're looking for Math.pow():

alert(Math.pow((0.03+1), (271/365))-1);

Math.pow( (0.03+1), ((271/365)-1) ) will give you a result of 0.9924164970995866

I interpreted the original expression differently, with -1 being applied after exponentiation. Then the result would be `0.022188992012574182`. Not sure which of us is correct? – bfavaretto Mar 26 '13 at 22:22
Hmm, fair point. My assumption was OP intended everything after the caret to be the part of the exponent. That *does* change things quite a bit though, you are correct! – couzzi Mar 26 '13 at 22:33
