How to calculate logarithm base 2 of -3/6 (or 1/2) for example?

[Ike Haze]

I know that there is lg function for logarithm base 2.

I tried several ways of inputting my formula:

lg(-3/6)

-3/6 lg

Always gives me NaN

How do I do it?

IIRC, the logarithm function is only defined for strictly positive numbers. So that SpeedCrunch can't give you an answer any more than if you asked for the result of 3/0 :-)
