Precision of floats is implementation dependant and AFAIR compiler is
allowed do float arithmetic at compile time with higher precision than
at host machine. What is result when floats are read from standard
input?

It is well-known that 'double' computation results on x86 processors can
carry excess precision. Namely, if the value is stored in a floating-point
register (80 bits total, 64 bits mantissa) without passing through a
memory store, it can carry excess precision. The two ways to prevent
such excess p
