Conversions Between Floats, Doubles, and Long Doubles
* When a long double is converted to a double or float, or when a
double is converted to a float, the original value is rounded to
the nearest representable value of the new type. If the original
value is equally close to two distinct representable values, then
the value chosen is the one with the least significant bit equal
to zero.
* Conversions between floating-point types involve a change in the
exponent, as well as the mantissa. It is possible for such a
conversion to overflow.
