{WP34S] Minor stats bug Message #1 Posted by Nigel J Dowrick on 30 Oct 2011, 11:22 a.m.
I'm running Build 1784 (on the actual calculator, not the emulator.)
The function NORML returns the cumulative normal probability distribution from negative infinity up to its argument, for a distribution with mean stored in register J and spread in register K.
When J contains 1 and K contains 10^40, NORML returns 0 for an argument less than 1, 0.5 for an argument of 1, and 1 for an argument greater than 1. This is correct behaviour.
However, when J contains 1 and K contains 0, NORML simply returns its argument, whatever that argument is.
This is unlikely to be a problem, but I think it's a bug!
