Strange normaliziers in BitcoivEnv

[anarlavrenov]

What is the purpose of such additional multiplications? (2 ** -15 etc)

normalized_tech = [
self.day_tech[0] * 2**-1,
self.day_tech[1] * 2**-15,
self.day_tech[2] * 2**-15,
self.day_tech[3] * 2**-6,
self.day_tech[4] * 2**-6,
self.day_tech[5] * 2**-15,
self.day_tech[6] * 2**-15,
]
state = np.hstack(
(
self.account * 2**-18,
self.day_price * 2**-15,
normalized_tech,
self.stocks * 2**-4,
)
