2.5 is a float.
Float stands for floating point. Floating point types are numbers with decimal places. I hope this helps!
Based on my personal experience in the workforce, all of the above would be the correct answer. That's based off my experience though. Owners would regularly come in and talk to our managers and employees to make sure everything was kept in order and in compliance. The only other answer I could see fit would be supervisors. Hope I was able to help :)
I will write a very short story, so I hope this helps a little
The processing of gold: A diary entry
April 5/2018
I am the worlds most precious metal.
I am worth more than any silly diamond, and far more stronger than Iron. No one can come close to being as important as I.
I start as a tiny mineral, found underground where I spend my days perfecting myself. Most might find relatives of mine in water, buried among sand and dirt. Then we are put through the most rigorous of training until we are god.
Well, gold, but you know what I mean.
Once I am perfection, I will be sold among the masses of people. I will be loved my all and crafted into everything. If I wanted, I could take over the world...a world of just gold, wouldn't that be magical?
Today I think I will be made into a ring, I hope I am not squeezed on some fat woman's finger.
I hope this helps a little, Cheers :)
