[erlang-questions] binary_to_float changes between OTP 19 and OTP 20

[Manuel A. Rubio]

Hello,

I was trying this code:

float_to_binary(2.7182818284590452354, [{decimals, 14}, compact]).

And I've realized that in OTP 19.3 I have this value:

<<"2.71828182845905">>

While in OTP 20.3 I've this other value:

<<"2.71828182845904">>

Even I was checking since OTP 17 until OTP 20.3 and looks like the 
change was in OTP 20.3 only. Why this change? Was it not correct in the 
previous versions or is it not correct now?

Thanks.
Manuel Rubio.
