Conversion from int or long to float, or long to double can lead to loss of precision (loss of least significant bits). In this case, the resulting floating-point value is a rounded version of the integer value, using IEEE 754 round-to-nearest mode. Despite this loss of precision, the Java Language Specification requires that the conversion and rounding occur silently, that is, without any runtime exception. See the JLS, §5§5.1.2, "Widening Primitive Conversion" for more information.
