Can't believe it's taken this long to notice this. Calculator can't perform x^y (x to the power of y). You have to rewrite as 10^(y * log(x)). For that matter nor does it calculate ln(x) (natural log). Wh .. aa .. t??

I've used a Z10 for years and can't for the moment regress, but I can't remember this blinding gap. Are the calculators different (surely not: both BB10)?

Or am I missing something truly evident to all but me?
