I am assigned some old code and when I was reading through it, I noticed it had these in the form of:
float low = 1e-9;
float high = 1e9;
float lowB = 1e-9;
float highB = 1e9;
float lowL = 1e-9;
float highL = 1e9;
So I see that it's trying to define some ranges using the e notation, right? But isn't 1e-9
supposed to be -1e9
?
Then the values would be between -1000000000
and 1000000000
, right?
I am not sure what 1e-9
is meant for?
