Question

It obviously depends on the context you are using them in but, I was wondering if there is a universally accepted way to name such variables, or at least in a mathematical context.

I’ve often seen:

float k         = someValue; float oneMinusK = 1 - k; 

…which seems as descriptive as much as meaningless to me.

Please note that I’m not asking how to name a variable, but how to do it in this very case. Examples and contexts where you used them will be much appreciated,

Thanks.

Answer 1

In probability 1-k is the probability of X not occurring, given that k is the probability of X occurring.

So

float will_win_lottery = 0.00000000001; float will_not_win_lottery = 1 - will_win_lottery;
