• DMI_LONG_BITS_TO_DOUBLE_INVOKED_ON_INT

“The Double.longBitsToDouble method is invoked, but a 32 bit int value is passed as an argument. This almostly certainly is not intended and is unlikely to give the intended result. ” – 2013-11-25

The method Double.longBitsToDouble(long l) does not complain if you pass an int value instead of a long value since, in general, longs can be constructed out of ints. In this case though not the value but the bits are important, therefore the constructed long might have a different effect as intended.

In any case one should never pass an int to this method. There is no good fix for this, that's why we don't offer one.

<code Java>

int i = 1003;
System.out.println(Double.longBitsToDouble(i));

Integer ii = new Integer(123);
System.out.println(Double.longBitsToDouble(ii));

</Code>

<code Java>

long l = 1003;
System.out.println(Double.longBitsToDouble(l));

</Code>
